摘要： The present invention is an indirect matrix converter capable of improving the accuracy of current detection. A converter (1) receives input of an AC voltage, converts the AC voltage into a DC voltage, and applies the DC voltage between a power line (LH) on a positive electrode side and a power line (LL) on a negative electrode side. A snubber circuit (2) has a capacitor (C1) provided between the power lines (LH, LL), and a diode (D1) connected in series with the capacitor (C1) between the power lines (LH, LL), and including an anode on a side close to the power line (LH) on the positive electrode side in a series path with the capacitor (C1). An inverter (3) converts the DC voltage into an AC voltage, and applies the AC voltage to an inductive load (8). An inverter-side current detection unit (4) detects a current that flows through the power line (LH) on the positive electrode side or the power line (LL) on the negative electrode side between the inverter (3) and the snubber circuit (2).

摘要： The present invention provides a power converter, wherein operation power supply for switching elements for sections other than a power converting section can be obtained from operation power supply for the switching element for a power converting section. A power supplying section (Cby1) is an operation power supply for a switching element (Ty1) for an inverter (3), and one end on a low potential side is connected to one end of the switching element (Ty1) on a DC power supply line (LL) side. A boot capacitor (Cbx1) is connected to one end of the switching element (Tx1) on a DC power supply line (LH) side, where the other end is electrically connected to one end of the power supply section (Cby1) on the high potential side. A diode (Dbx1) is provided in a path extending from one end of the power supply section (Cby1) on the high potential side to the DC power supply line (LH) via the boot capacitor (Cbx1). The diode (Dbx1) makes only the current, which is flowing from the power supply section (Cby1) to the boot capacitor (Cbx1), flow.

摘要： The present invention provides a power converter, wherein voltage fluctuations of an operation power supply of a switching element of a converter are suppressed. A switching element (Tr2) connects/disconnects an input end (Pr) to/from at least either of power supply lines (LH, LL). A switching element (Tr1) is provided between the power supply lines (LH, LL). One end on the low potential side of a power supply unit (Cbr1) is connected to the switching element on the side of either of the power supply lines (LH, LL). One end of a capacitor (Cbr2) is connected between the switching element (Tr1) and the input end (Pr). The other end of the capacitor (Cbr2) is connected to one end on the high potential side of the power supply unit (Cbr1). The capacitor (Cbr2) and the power supply unit (Cbr1) respectively serve as operation power supplies for outputting switch signals to the switching elements (Tr2, Tr1). A voltage adjustment unit (CCr) maintains voltage across both ends of the capacitor (Cbr2).
