Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a control device of a power conversion apparatus capable of determining which system in multiplex-system gate pulses is abnormal.SOLUTION: There is provided a gate pulse generator 1 configured to ignite a thyristor 22 by duplex-system gate pulses GPa, GPb. When gate pulses GPa, GPb of a system that ignites the thyristor 22 first are selected from duplex-system gate pulses GPa, GPb, ignition of the thyristor 22 is detected, and the detected ignition of the ignition thyristor 22 is determined as not being performed by the gate pulses of the system that ignites the thyristor 22 first, the system is determined as being abnormal.
