トパフ１ス発生回路。A line voltage signal extracted from the three-phase voltage signal of the three-phase AC power supply of the thyristor conversion circuit, a first synchronization signal obtained by crossing each of the three phases from this line voltage signal on the positive side of the frequency, and the negative side. In the gate pulse generation circuit, the gate pulse signal of the thyristor conversion circuit is obtained by time measurement by a microcomputer and a timer circuit using the second synchronization signal crossed at the second synchronization signal and the output control signal of the thyristor conversion circuit.
When the synchronization signal is given, the control amount is calculated for the control signal, the result is preset in the second timer circuit, and the second synchronization signal is used to calculate the control amount for the control signal. A gate pulse signal is generated by measuring the time, and when the second synchronization signal is given, the control amount is calculated, and the result is preset in the first timer circuit. 1. A gate puff generation circuit characterized in that the first timer circuit is configured to generate a gate pulse signal by measuring time with respect to a first parallel signal.
