INDIRECT MATRIX CONVERTER

A converter receives input of an AC voltage, converts the AC voltage into a DC voltage, and applies the DC voltage between a first power line on a positive electrode side and a second power line on a negative electrode side. A snubber circuit has a capacitor provided between the first and the second...

More Information
Summary:A converter receives input of an AC voltage, converts the AC voltage into a DC voltage, and applies the DC voltage between a first power line on a positive electrode side and a second power line on a negative electrode side. A snubber circuit has a capacitor provided between the first and the second power lines, and a diode connected in series with the capacitor between the first and the second power lines, and including an anode on a side close to the first power line on the positive electrode side in a series path with the capacitor. An inverter converts the DC voltage into an AC voltage, and applies the AC voltage to an inductive load. An inverter-side current detection unit detects a current that flows through the first power line on the positive electrode side or the second power line on the negative electrode side between the inverter and the snubber circuit.
