Abstract

PURPOSE: To make it possible to exercise control over the voltage and current of load capacity nearly 31/2 times, by inserting switching elements such as reverse- parallel thyristors and triacs in series among primary-side or secondary-side terminals of a ΔΔ connection transformer.
CONSTITUTION: Respective reverse-parallel thyristors 3a, 3b and 3c are controlled in the same gate phase with a phase difference of 120 degrees by a gate phase control circuit. On the secondary side of ΔΔ connection transformer 2, reverse-parallel thyristors 3a, 3b and 3c are connected in series in a triangle. The secondary current of transformer 2, i.e. a thyristor current waveform includes a higher harmonic, and consequently although it becomes greater than 1/31/2 as much as a line current, current ratio K to various gate phase angles (α) is within the range of 1/21/2≤K≤ 1/31/2. Therefore, the load capacity of nearly 31/2 times can be controlled by an identically-rated element.
