摘要：

Miniaturization and lightening of pulse power supply (PPS) is a key technique in electromagnetic launch. Semiconductor switch module in PPS takes up a large volume. To obtain a compact and small semiconductor module, a method to miniaturize the module by reduce the thickness of copper substrate of thyristor is proposed. And its thermal model is established to analyze its instaneoμs temperature field. Based on the simulation results, it is found that the copper substrate thickness of thyristor does not affect the peak junction temperature, but affects the final time to cool slightly. According to the theory basis, a prototype of thinner thyristor is produced. It is proved that the thinner thyristor has the similar current capacity and di/dt capacity with conventional type.
