Abstract

PURPOSE:To obtain a device having a few circuit components and high reliability and easy supervision for faults by composing a gate logic circuit of programmable digital elements wherein the parity check for output is performed at an external section. CONSTITUTION:Firing pulses TP are supplied to the control rectifier elements in a power converter from a gate logic circuit 24 by the output signal COM in a digital comparator 23 comparing the phase synchronous signal theta1 from a digital phase detector 21 with the control signal delta1 from a digital arithmetic unit 22 and a phase decision signal theta2 and an angle signal delta2. The gate logic circuit 24 is composed of an ROM, a sex counter 52, and a parity checker 53, for example, to consist the outputs TPU-TPY in the ROM51 of even or odd parity. And the abnormality in the circuit 24 is supervised by performing parity check.
