Abstract
PURPOSE:To perform stable ignition control even when a load is fluctuating by a method wherein the half-wave of phase voltage on the primary side of a transformer for rectifier is compared with the voltage converted from load power and a counter circuit is made to operate correspondingly by the output through comparison to control the thyristor. CONSTITUTION:Double star connection is applied to the secondary side of the transformer for rectifier and the thyristors 3 are inserted to each phase thereof to subject the gate thereof to the phase control, whereby DC power is supplied to a load 4. A gate controlling circuit 8 compares the output through detection of the half-wave of the phase voltage on the primary side of the transformer for rectifier through the intermediary of a transfomer 9 with the output of an adjusting apparatus 5 to which load voltage and current are inputted in a comparison circuit 17 and makes the counter circuit 12 counting a clock signal from a reference frequency oscillator 10 operate correspondingly, thereby controlling each thyristor 3. Accordingly, the ignition control can be performed in a proper phase without requiring adjustment of unbalance of each phase even when the load is fluctuating.
