Title: Power supply circuit arrangements
IPC: H02M7/537
Filed: 1975-09-22
Abstract: 1528358 Automatic voltage control SIEMENS AG 22 Sept 1975 [20 Sept 1974] 27057/75 Heading G3R A power supply circuit comprises a switching transistor T connected in an oscillatory circuit formed by transformer winding L1 and capacitor CS and supplied from a voltage UB. The transformer includes a secondary winding L2 which supplies the D.C. output voltage VA and a third winding L3 which acts as a monitoring winding of the currents in windings L1 and L2. Winding L3 is connected through resistors R4, R5 to the voltage supply UB and to the negative supply and provides a voltage at capacitor C1. A divider arm comprising resistor R1 and Zener diode D2 defines a reference level for application to comparator V1 and resistors R2, R3 provide a signal representing the actual value of voltage VA which is taken to comparator V1. The output of comparator V1 regulates transistor T to alter the current passing through switching transistor T2 to transistor T. Transistor T2 is switched on and off by comparator V2 which is connected to the connection point of R4, R5. This junction point is arranged to be near zero volts by using resistors which match the transformer winding ratios. The other input of comparator V2 is connected to the negative line so that the collector-emitter voltage of transistor T is monitered. In operation transistor T2 is switched on when the oscillating collector voltage reaches zero or a level less than zero and transistor T then conducts when the voltage goes positive to build up a field in winding L until the collector voltage exceeds the value set by comparator V2 when it is switched off. The capacitor CA is then subsequently charged by the discharge of the energy in winding L1 to resistor voltage VA to the desired value. In a modification of the basic circuit, Fig. 4 (not shown), a driver amplifier stage is added to control transistor T2 together with a start feedback circuit which provides rapid current rise in the oscillatory circuit and a switch-on circuit to produce the voltage supply to the control circuit.
