摘要：

 针对高压高频大功率应用场合高压变压器寄生参数对变流器工作过程的重要影响,变流器采用了谐振式工作方式,利用高压变压器的漏感和寄生电容组成了并联谐振网络.为了减小高频大功率条件下功率器件的开关损耗,采用断续电流模式,实现了功率器件的零电流开通和零电压零电流关断.通过对容性滤波并联谐振变流器断续电流模式的分析和数学描述,推导得到了变流器特性的解析表达式,详细分析了变流器的稳压和调压特性,分析结果为高压高频大功率应用场合变流器的设计提供了理论依据.构建了一台50 kV/22 kW的实验样机,通过实验验证了理论分析的正确性.

Abstract:

The parasitic parameters of high voltage, high frequency and high power transformers have important influence on converter operation. So the converter adopts resonant operation and makes use of leakage inductance and parasitic capacitance of the high voltage transformer as parallel resonant tank. In order to reduce switching losses of the power switches, discontinuous current mode（DCM) was adopted. So zerocurrent switching（ZCS) turnon and zerovoltage, zerocurrent switching（ZVZCS) turnoff of the power switches were achieved. By mathematic analysis of converter operation, an analytical expression was derived to describe characteristics of the converter. The voltage regulation was given in detail. The results give guidance for the design of parallel resonant converter in high voltage, high frequency and high power applications. A 50 kV/22 kW output prototype was built to verify the theoretical analysis.
