Abstract: PURPOSE:To protect a switching element against breakdown due to variation of load voltage by detecting the voltage on the input winding of an output transformer and controlling switching elements based on thus detected voltage. CONSTITUTION:Power from a DC power supply 13 is inverted through a half- bridge inverter 21 into an AC power which is fed through an output transformer 27 to a discharge lamp 29. Voltage on the primary winding 27a of the output transformer 27 is detected by means of a voltage detecting circuit 31 through a voltage detection winding 27c and compared with a reference value, and a control circuit 32 controls ON/OFF operation of switching elements 22, 23 thus controlling the output voltage. When the detected voltage exceeds a predetermined level, a safety circuit 33 interrupts oscillation of the control circuit 32 thus protecting the circuitry.

Title: Power factor improving method for step-down chopper
Inventor: WATANABE HARUO
IPC: H02M3/155
Filed: 1992-02-04
Abstract: PURPOSE:To make it possible to always operate with a high conversion efficiency by limiting the operation range of time ratio and thereby preventing the worsening of power factor in a step-down chopper circuit having AC full- wave rectifying output as a power supply. CONSTITUTION:An output voltage V1 of an AC power supply E is full-wave- rectified by a full-wave rectifying circuit REC, applied directly to a step-down chopper circuit comprising a switch element Q1, diode D1, chopper coil L1 and a capacitor C1 and then supplied to a load RL. Also, the switch element Q1 is ON/OFF-controlled by the output of a control circuit CONT having an output voltage Vo as control input, and the output voltage Vo is kept constant. In this step-down chopper circuit, the ratio of gate control signal of switch element Q1, at the time when it is maximum, is set to a value smaller than the result obtained by dividing the output voltage Vo by the maximum value of a power supply voltage V1. By doing this, flow of a surge-like current can be prevented and the worsening of power factor can be also prevented.

Filed: 1979-04-18
Abstract: PURPOSE: To generate a sequence of codes including no DC component by coding and outputting the coding output and opposite value of one past input value 0 of a state transition.  
     CONSTITUTION: Data 0, when inputted from input terminal 1, is inverted by NOT circuit 4d into 1 to invert by NAND circuit 8 one past signal 0 stored in FF3. At this time, since AND circuit 5d following circuit 8 is closed, inversion signal 1 of one past signal 0 is outputted to output terminal 2 via OR circuit 6c. When 1 is inputted from terminal 1, on the other hand, 1 is coded by MFM coder 9. In this case, circuit 5d following coder 9 is opened and AND circuit 5e follwing circuit 8 is closed, so that 1 coded by coder 9 will be outputted to terminal 2. Then, initial 0 and final 0 of the state transition at this time in small sequence of 0, 1,...1, 0 is coded by inverting by added transition to remove a DC component.
