摘要： A power converter circuit includes a diode group, a relay, a DC section and an inverter. The diode group includes a plurality of diodes arranged to rectify an output voltage of an alternating-current power supply. The relay is provided at a point located closer to the alternating-current power supply than the diode group. The DC section is where an output voltage of the diode group is applied. The inverter is arranged to output a three-phase alternating-electric current to a three-phase load. The DC section has a maximum pulse voltage twice as great as a minimum pulse voltage of the DC section. The DC section includes an energy-absorbing circuit having an electrolytic capacitor. The DC section further has a pathway arranged to apply the output voltage of the alternating-current power supply from the alternating-current power supply to the electrolytic capacitor via a rectifying circuit, not via the relay.

摘要： In the case where a chip is made of wide band gap semiconductor, a power conversion apparatus is obtained in which a component having a low heat resistant temperature is prevented from receiving thermal damage by heat generated at the chip. In a configuration including: a chip portion (20) including a chip (21) made of wide band gap semiconductor and a member (22, 23) having a heat resistant temperature equal to or higher than that of the chip (21); and a peripheral component (25) arranged in the vicinity of the chip portion (20) and having a heat resistant temperature lower than that of the chip (21). The chip (21) and the peripheral component (25) are thermally insulated from each other so that the temperature of the peripheral component (25) does not exceed the heat resistant temperature of the peripheral component (25).
