Abstract

The invention discloses a power module, comprising a first power device and a second power device, wherein each power device comprises at least two electrodes, and a power supply converter used in the power module has the power density being greater than 15w / inch<3> and the highest efficiency being higher than 92%, or the power density being greater than 20w / inch<3>, or the highest efficiency being higher than 93%. The working frequency of at least one of the power devices is above 25kHz. Consequently, not only can the cost be saved, but also the space utilization rate can be increased, and the performance of the power supply converter is further improved.

Description

technical field [0001] The present invention relates to a power module, in particular to a power module applied in a power converter. Background technique [0002] High efficiency and high power density have always been the industry's requirements for power converters. High efficiency means reducing energy consumption, which is conducive to energy conservation, emission reduction, environmental protection, and reduction of use costs. High power density means small size and light weight, reducing transportation costs and space requirements, thereby reducing construction costs; high power density also means reducing the amount of materials used, which is further conducive to energy conservation, emission reduction and environmental protection. Therefore, the pursuit of high efficiency and high power density in the field of power supply will never stop. [0003] There are many types of power converters due to their different uses. Divided by the type of converted electric en...
