Definitions
- the present invention relates to an inverter that converts a DC voltage into an AC voltage and a power converter such as a converter that converts an AC voltage into a DC voltage.
- Patent Document 1 discloses that the use of an element made of a SiC semiconductor as a main switching element can increase the carrier frequency of PWM control and can improve the efficiency compared to the conventional configuration. Yes.
- Wide bandgap semiconductors such as the above-mentioned SiC semiconductors have a dielectric breakdown electric field about 10 times higher than that of conventional Si semiconductors, which makes it easy to increase the breakdown voltage of the device, and the same breakdown voltage. Since the device thickness can be reduced compared to the case of Si semiconductor, the conduction loss is small and the device can be made small.
- Patent Document 1 JP-A-2006-42529
- the present invention has been made in view of such a point, and an object of the present invention is to prevent the heat-resistant temperature from being generated by the heat generated in the chip even when the chip is formed of a wide band gap semiconductor. Try to obtain power converters that are configured so that low components are not thermally damaged.
- the peripheral component (25) having a low heat-resistant temperature is thermally caused by the heat of the chip (21) made of a wide band gap semiconductor.
- the peripheral component (25) and the chip (20) including the chip (21) were thermally insulated from the heat resistant high V and the chip part (20).
- the wide band gap semiconductor chip (21) and a member (22, 23) having a heat resistance temperature equal to or higher than that of the chip (21) are configured.
- a power conversion device including a chip portion (20), a heat resistant temperature lower than that of the chip (21), and a peripheral component (25) located around the chip portion (20). To do.
- the chip part (20) and the peripheral part (25) are thermally insulated so that the temperature of the peripheral part (25) does not exceed the heat resistance temperature of the peripheral part (25).
- the thermal insulation includes a material that suppresses heat transfer that does not completely block heat transfer.
- the chip (21) made of a wide band gap semiconductor can be operated under high temperature conditions, and the chip (21) can be downsized and operated at high speed.
- the chip portion (20) guides the heat of the chip (21) to the heat dissipation means (23) and the heat dissipation means (23) for radiating the heat of the chip (21). And at least one of the heat transfer member (22) and the heat dissipating means (23) via the heat insulating member (24) as the heat insulating means. It shall be supported by peripheral parts (25) (second invention).
- the heat generated in the chip (21) is radiated from the heat radiating means (23) via the heat transfer member (22), and thus the temperature of the chip (21) is efficiently reduced. be able to.
- the heat insulating member (24) is a heat-resistant adhesive for bonding the peripheral component (25) to at least one of the heat transfer member (22) and the heat dissipating means (23).
- the heat insulating adhesive is preferably a polyimide-based ceramic.
- the thermal insulation means (26) is a heat shield (26) provided so as to suppress heat radiation from the tip portion (20) to the peripheral component (25). Liked! /, (4th invention). By providing the heat shield plate (26) in this way, heat radiation from the chip portion (20) can also be blocked, and the temperature rise of the peripheral component (25) can be reliably suppressed.
- a package (41) enclosing a wide bandgap semiconductor chip and a pattern (44) to which a terminal (42) of the package (41) is connected are provided.
