たことを特徴とする電力変換器の制御装置。 A sawtooth wave generator synchronized to an alternating current power supply for firing angle control in a power converter having a plurality of controllable electric valves and operating in connection with an alternating current power supply; A power converter equipped with a firing angle adjustment circuit comprising a comparator that generates a firing signal for the corresponding controllable electric valve by comparing the output signal of the device with a control input signal that commands the firing angle. In the control device, the above-mentioned firing angle adjustment circuit is provided only for one controllable electric valve as a reference, and the remaining controllable electric valves are provided with a set time corresponding to the phase difference with respect to the reference controllable electric valve. A control device for a power converter, comprising: a timer circuit that starts a timed operation in response to a firing signal from the firing angle adjustment circuit and issues a firing signal after the set time period has elapsed.
