Abstract: PURPOSE:To enhance the efficiency of a device and reduce the cost, by using a capacitor, and by permitting gate current to flow to a thyristor. CONSTITUTION:So far as a DC/AC inverter is concerned, DC input current V11 is turned ON/OFF by a transistor Tr 11 via an input switch S11, a thyristor Sr 11, and the primary winding T11-1 of a transformer T11, and from the secondary winding of the transformer T11, the output of specified voltage is generated. So far as the rush current limiting circuit of the inverter is concerned, when the input switch S11 is closed, then the thyristor Sr 11 is OFF, and so through a resistor R11, current flows to a first capacitor C11, and its voltage is slowly heightened, and the Tr 11 starts ON/OFF-working. When the Tr 11 is ON, then current flows to a second capacitor C12 through a diode D12, and when the Tr 11 is turned OFF, then electric charge is discharged, and the electric charge is stored in the reverse direction. Accordingly, when the Tr 11 is turned OFF again, then charging current flows to the second capacitor C12, and through a diode D11, the gate current of the thyristor Sr 11 flows.
