高功率高密度机载开关电源变压器的热设计

Thermal Design of High Power and High Power Density Transformer for an Airborne Switching Power Supply

在某型机载相控阵雷达中,阵面电源采用移相控制零电压开关PWM变换技术。该电源功率大,功率密度高,高功率变压器的热设计十分复杂。以下介绍了该电源的变压器热设计过程。

In a high power, high power density airborne switching power supply the PS-ZVS PWM converting technique is applied. It has high power volume and high power density ,and the thermal design of such a powerful transformer is very complex. This paper describes the details of thermal design process for the transformer.
