Abstract

PURPOSE:To reduce the control responsibility of an AC source by giving a thyristor circuit the current sharing control function. CONSTITUTION:When the output voltage of inverter equipments 11 and 12 is -Vd and the load current flows through thyristors 221 and 222, if the output voltage of inverter equipments 11 and 12 is reversed from -Vd to +Vd at the time to the output current of each inverter will decrease and become zero at the time t1 and t1'. Then, when thyristors 211 and 212 are ignited, for instance, if the inverter equipment 12 bears more current burden than the inverter equipment 11, the thyristor 211 will be ignited at the time t2 and the thyristor 212 will be ignited at the delayed time t2'. As a result, the current burden of the inverter equipment 12 will be reduced and, on the other hand the current burden of the inverter equipment11 will be increased, so that the load will be shared evenly by both equipments.
