摘　　要：以四元系PMMN压电陶瓷变压器为升压器件,以脉宽调制器(PWM)和MOSFEET管所组成的开关振荡器为驱动电路,研制出适用于雷达显示系统的多路输出10kV压电陶瓷变压器高压电源.由于压电陶瓷变压器具有许多优点,不仅提高雷达整机的可靠性,而且能适应当前军事产品小型化、机动性强的发展需要.A high voltage power supply stepping-up voltage to 10kV by using PMMN quaternary piezoelectric ceramic and drived by pulse width modulation (PWM) and MOSFET is introduced. PCT has many novel features:small in size,light in weight,it can't be burnt while the load circuit is shortened. These advantage not only enhance the working reliability of radar overall but also meet the development demands to make the military productions minimized,lighten and flexible.
