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 certain type of airborne phased array radar, the front-end power supply adopts phase-shifting control zero-voltage switching PWM technology. The power supply, high power density, high power transformer thermal design is very complicated. The following describes the power transformer thermal design process.
