Abstract

PURPOSE:To normally operate the circuit under any load condition, by adding a rectifying element to block charging to capacitors due to the electromotive force a load. CONSTITUTION:When a pulse voltage is fed to a switching element 6 from a pulse generating circuit 3 at zero voltage period of one AC period, the element 6 is conductive and electric power is fed to a load through the formation of a circuit consisting of a load 2, rectifying element 10 and element 6, from an AC power supply 1. In this case, a capacitor 4 is charged with a circuit consisting of a resistor 9, rectifying element 7, capacitor 4 and element 6 at the same time, and this charging voltage is fed to the load at the remaining semi-period. When the application of pulse voltage to the gate of the element 6 is stopped, the charging of electromotive force of the load to the capacitor 4 is blocked with the rectifying element 10, then no switching element 5 is triggered and the supply of electric power to the load 2 is all interrupted.
