Title: Circuit for constant-voltage power supply
Inventor: ENDO TOSHIO
IPC: G05F1/56
Filed: 2000-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a circuit for constant-voltage power supply that can fall a power rapidly even though it has a ripple absorption condenser. SOLUTION: When switches of S1 and S2 are 'on' in the direct current circuit 1, a npn transistor Q1 becomes 'on' and a pnp transistor Q3 becomes 'off', the lower constant-voltage-that a power supply voltage V2 is outputted from line L2. A condenser C2 installed between a line L2 and the earth eliminates output voltage ripples on the direct current circuit 1. When both switches S1 and S2 are 'off', a bias capacitor C1 discharges electricity, a transistor Q4 becomes 'on'. The npn transistor Q1 becomes 'off', at the same time, the pnp transistor Q3 becomes 'on', then the capacitor C2 discharges electric charge. These make the output voltage to fall rapidly. The continuity start time of the transistor Q4 can be decided aribitrarily by the setting of the resistance value of resister R9 and R10.
