发明名称 Heat sink for electrical power converter
摘要 In order to prevent an increase in temperature of a discharge resistance discharging an electric charge accumulated in a smoothing capacitor, the present description discloses a power module. The power module has a first lead frame, a second lead frame, first and second semiconductor switches connected in series between the first lead frame and the second lead frame, a resistor connected between the first lead frame and the second lead frame, and a resin package that encapsulates the first lead frame, the second lead frame, the first semiconductor switch, the second semiconductor switch, and the resistor. In this power module, a radiator portion for radiating heat from the first lead frame and/or the second lead frame is formed in at least a part of the package.
