Abstract
PURPOSE: To control converting power by employing the difference between the output voltage and highly set input voltage as control voltage, then performing voltage conversion on it at voltage converter in switching system and feeding back to the input side.
CONSTITUTION: Voltage converter comprising capacitors 12, 14, switching transistor 8 and inductance coil 11 is connected between DC power source 3 and the load 4, and the voltage Vc1 across the capacitor 12 is employed as input voltage of said voltage converter while voltage Vc2 across the capacitor 14 is employed as output voltage. Consequently as the input voltage increases it is detected by error amplifier 5 while pulse width modulator 6 shortens the turning-on time of transistor 8 to increase Vc1 and to decrease the output voltage thus to maintain the output voltage constant. Consequently voltage is stabilized with reduced control loss.
