Title: Voltage control circuit for pulse width modulation power soruce
Inventor: SAKAMOTO MASAHARU
IPC: H02M3/335
Filed: 1978-07-12
Abstract: PURPOSE: To always obtain a maximum output, by reducing an output voltage in proportion to a load larger than a prescribed level when the load is applied to a power supply circuit.  
     CONSTITUTION: A control circuit 4 is provided to compare the output voltage of a rectifier circuit D with a reference voltage to control a pulse width modulation circuit 3 and regulate the switching action of a switching circuit 1 by the output of the modulation circuit. When a load current has exceeded a prescribed level I, the voltage drop through a resistor P1 increases and a transistor Q1 is turned on. A collector current proportional to the voltage drop flows through the transistor so that the potential on a point A, namely, the reference voltage is reduced by the current mirror action of other transistors Q2, Q3. As a result, the pulse width modulation circuit 3 is supplied with a signal for reducing the pulse width and the output voltage falls in proportion to the increase in the output current. Therefore, the maximum output corresponding to a load of prescribed impedance is obtained even if a load of lower impedance than the former is connected to the rectifier circuit D.
