摘要： A power regeneration device according to an aspect of embodiments includes a voltage detecting unit, a signal processing unit, a phase detecting unit, and a power conversion unit. The signal processing unit generates, by using self-oscillation when the output of an AC detection signal from the voltage detecting unit is stopped due to a power outage, an AC signal whose frequency is the same as that of and whose phase is continued to that of the AC detection signal just before the stop. The phase detecting unit detects the phase of the AC power supply on the basis of the AC signal from the signal processing unit when power is recovered from the power outage.

摘要： A matrix converter includes a plurality of semiconductor switch modules, and a plurality of snubber modules each having a plurality of capacitors and a plurality of diodes. Each of the snubber modules has a terminal group projecting outward, a first terminal, and a second terminal. The first and second terminals project from positions different from the terminal group, and are connected to an external circuit provided outside the matrix converter. Terminals of the terminal group are connected to terminals of a corresponding semiconductor switch module. The first terminals of the plurality of snubber modules are connected to one another via a first bus bar, and the second terminals are connected to one another via a second bus bar.

摘要： A matrix converter includes a matrix converter main circuit, an input voltage detector group configured to detect an input voltage of an alternating current source, a gate driver configured to drive a bidirectional switch, and a controller having a pulse width modulation operation unit and a commutation operation unit. The pulse width modulation operation unit is configured to fix one output phase in a conduction state, configured to pulse-width-modulate one of remaining two output phases by using all three input phases, and configured to pulse-width-modulate the other output phase by using only two input phases of a reference input voltage and a middle input voltage.
