Abstract

PURPOSE:To make a pulse transformer unnecessary, by a method wherein the rush current limiting resistor of a smoothing capacitor is short-circuited by a thyristor and the gate control current of the thyristor is used both for the control power source of the minus side group of the transistor of an inverter. CONSTITUTION:An inverter controller is constituted of the rush current limiting resistor 5 of a smoothing capacitor 4, a thyristor 3a as well as a diode 3b for short-circuiting the resistor 5, a photocoupler element 7a for controlling ignition, transistor groups 12'-15', the base control power sources 12-15 of the transistor groups. Upon applying AC power sources R-T, a rush current for the smoothing capacitor 4 is conducted from a converter 1, therefore, the rush current is limited by said resistor 5, connected in series to the converter 1, while said resistor 5 is short-circuited by the thyristor 3a to start the opera tion of the inverter controller. The thyristor 3a is connected to the rectifier 22 of the control power source to ignite it by the power source through the photocoupler element 7a.
