     For the requirement of application, FIG. 3 show the Master Switch Circuit  100  and Ignition Circuit  200  is taken from FIG. 1 as an independent Circuit. Because the AC input of the Invention is sent through Full Wave Bridge Rectifier  103 , the Inverse Circuit of the Master Switch Circuit  100  can be saved.

FIG. 6B shows the output waveform of the A Terminal and B Terminal of FIG.  5 . FIG. 6A shows the waveform of Terminal  1  and Terminal  2  of FIG.  1 . 
     FIG. 7 shows the Second Timer Control Circuit. Power Source Circuit  400 , Timer Control Circuit  500 , Switch Circuit  600 , and Current Transformer Circuit  700  compose the Second Timer Control Circuit. The Input Terminal of Power Source Circuit  400  is the Primary of Transformer  401 , Terminal  1  and Terminal  2 . The Secondary of the Transformer  401  is connected to the two AC Terminal of Full Wave Bridge Rectifier  402 ; the Positive Terminal of Full Wave Bridge Rectifier  402  is connected to one junction of the Step-down Resistor  403 . The other junction of Resistor  403  is connected to the Input Terminal of Voltage Regulator IC  406 , the Positive Terminal of the first Filter Capacitor  404 , and the N junction of Zener Diode  405 . The Output Terminal of the Voltage Regulator IC  406  is connected to the Positive of the Second Filter Capacitor  407 . The Negative Terminal of Full Wave Bridge Rectifier  402  is connected to the Negative Terminal of the First and the Secondary Filter Capacitor  404  and  407 , P junction of the Zener Diode  405 , and the Ground Terminal of the Voltage Regulator IC  406  as a common ground. After the AC Source from the Secondary of the Source Transformer  401  is sent through the Full Wave Bridge Rectifier  402 , the DC output of the Full Wave Bridge Rectifier  402  is sent to the Input Terminal of Voltage Regulator IC  406 , N junction of Zener Diode  405  and the Positive Terminal of the First Filter Capacitor  404  via Resistor  403 . The Input Voltage of Voltage Regulator IC  406  is equal to the voltage across the Zener Diode  405 . The Output Voltage of the Voltage Regulator IC  406  is the DC Power Supply of the Second Timer Control Circuit. The action theory of Timer Control Circuit  500  is the same as the First Timer Control Circuit. The only difference is that a PTC  503  is connected to the Turn-off Timer Coefficient Resistor  504  in serial. The purpose of the PTC  503  is when the Temperature of the Invention rises; the Ignition action has enough time to stop ignition. The DC Power Supply of the Invention Timer Control Circuit is supplied from Power Source Circuit  400 . A Compapator Circuit that composed by OP AMP IC  601  in Switch Circuit  600  executes the comparison between two input voltages. When the DC Voltage on Non-inverter Terminal is greater than the DC Voltage on Inverter Terminal in the Comparator Circuit  601 , the output of the Comparator Circuit  601  generates a DC Voltage. The DC Voltage from the output of the Comparator Circuit  601  is sent to the LED Terminal of Photo Coupling IC  610  via Step-down Resistor  608  and Filter Capacitor  609 . At this moment the LED of Photo Coupling IC  610  is on, the Transistor of Photo Coupling IC  610  is in on state. The DC Voltage is sent to the Positive Terminal of Filter Capacitor  614 , the Base of Control Transistor  613 , and one junction of Base Resistor  612  via Resistor  611 . The Collector and the Emitter of the Control Transistor  613  is in on State. Therefore the DC Voltage that sent to the Diode  616  via Resistor  615  is short-circuited by the Collector and Emitter of the Control Transistor  613 . At this moment, the Voltage that sent to the Divided Resistor  618  and  619 , and Resistor  617  can not make a Voltage on the Base of Switch Transistor  620  to turn the Collector and the Emitter of the Switch Transistor in Turn-off State. That is, the Coil of the Relay  621 , which is connected to the Collector of Switch Transistor  620  in serial, is not activated. The Junction of the Relay  621  is in off State; the Ignition is stop. In contrast, if the Inverter Voltage is greater than Non-inverter Voltage in Comparator Circuit  601 , the Invention executes the Ignition. The Voltage of the Inverter Terminal in Comparator Circuit  601  samples. from the center junction of Divided Resistors  602  and  603 . The Voltage of the Non-inverter Terminal in Comparator Circuit  601  samples from the Secondary of Current Transformer Circuit  700 . A Protection Circuit is connected to the Non-inverter Terminal of Comparator Circuit  601 . The purpose of this Protection Circuit is to ensure that the Ignition is not executed if the DC voltage is not stable in the beginning power supply. A PNP Type Transistor  607 , Divided Resistors  605  and  606 , and Zener Diode  604  compose the Protection Circuit. The Primary of the Current Transformer Circuit  700  is serial to the Load. When an AC Power adds on the Load, a current is sent to the Primary of the Current Transformer Circuit  700 ; the Secondary of the Current Transformer Circuit  700  generates an AC Voltage. The AC Voltage is sent to the AC Terminals of the Full Wave Bridge Rectifier  702 . A DC Voltage is got from the Positive Terminal of the Full Wave Bridge Rectifier  702  via the N junction of the Zener Diode  703 , Divided Resistors  704  and  706 , and the Positive Terminal of the Filter Capacitor  705 . The Voltage, which sent to the Switch Circuit  600 , is from the Center Junction Voltage of Divided Resistor  704  and  706 . The Negative Terminal of the Full Wave Bridge Rectifier  702 , the P Junction of Zener Diode  703 , the Negative Terminal of the Filter Capacitor  705 , and the other junction of the Resistor  706  is connected to the Common Ground. The function of this Division is that when the AC Voltage is not added on the load, the Division is 0 Voltage output. The Contact Point of Relay  621  of Switch Circuit  600  execute Turn-on action, the Ignition begins. When the Ignition successful, the Load Current makes the Switch Circuit  600  change state; at this moment the Relay is in Off State and stops the Ignition. The purpose of Timer Control Circuit  500  is to execute the Ignition Timing and the frequency of the Ignition action.

The Terminal A of FIG. 5 is connected to the Switch S. The Switch S switches to either Terminal  2  or  3  of Autotransforner  800  depended on application requirement. The Terminal  3 , the Output Terminal of Autotransformer  800  is connected to the High Voltage Diode  901  and  902  of the Load Circuit. Other High Voltage Diode may connect between High Voltage Diode  901  and  902  in serial and same direction. The number of the High Voltage Diode is depended on the DC Voltage of the Load Circuit  900  and not limiting. The number of Capacitors that connected between the Filter Capacitors  903  and  904  in same direction serial and is depended on the characteristic of Load  905 .

When a AC Voltage is sent to the Terminal O and P, the Secondary of Current Transformer  2001  senses a AC Voltage and sends to the AC Terminal of Full Wave Bridge Rectifier  2002 . The Positive Terminal is connected to the one junction of Step Down Resistor  2003 ; and the other junction of Resistor  2003  is connected to the N Junction of Zener Diode  2004 , the Positive Terminal of Filter Capacitor  2005 , and one junction of Divided Resistor  2008 . The Center junction of Divided Resistors  2008  and  2006  is connected to the Positive Terminal of Capacitor  2007 , and the Non-inverter Terminal of Comparator Circuit  2011 . If the Non-inverter voltage is greater than Inverter voltage, the Comparator Circuit  2011  generates a Voltage Output. The Voltage Output from Comparator Circuit  2011  makes the LED of Photo Coupling IC  2013  on via Current Limiting Resistor  2012 . The Collector and the Emitter of Photo Coupling IC  2013  are in Turn-On State; and make the Timer Control Circuit  300  in Off State. At this moment, the Master Switch Circuit  100  is in Off State.

The Auto Reset Circuit  1000  gives this Invention another protection option. The Auto-Reset Circuit  1000  works whenever the Ignition takes place. The Time Coefficient Capacitor charges once whenever the Ignition executes once. When the Ignition exceeds the Safety Limit of the Circuit, the Voltage Level of the Capacitor  1005  turn the Collector and the Emitter of the Transistor  1006  in ON State; therefore the Ignition is stop because the Gate of the MOSFET  104  is grounded.

The function of the Surge Protector is like the protection function of SIDAC or MOV to the power MOSFET. The Break Down Voltage of a serial numbers of power MOSFETs must be higher than the Break Down Voltage of a serial numbers of Surge Protectors. The IGBT (Insulated Gate Bipolar Transistors Modules) can be applied on this Invention instead of power MOSFET because both of them have the same characteristic.
