高压逆变电源系统在工作时,随着应用环境的变化,负载阻抗会发生变化,负载阻抗变化进而影响电源正常稳定工作。为理解负载阻抗的变化特性及规律,设计合适的逆变电源负载,本文根据实际应用的高频高压逆变电源电路,对负载阻抗的变化进行了理论分析和仿真,最后给出输出电压电流对负载阻抗的变化仿真曲线。根据曲线我们可以为系统电路参数的设计和选择提供依据。

When a high-voltage inverter supply works its load impedance will change with the application environment, thereby affecting the stable work of the power supply. In order to understand the variation characteristics and laws, so as to design suitable inverter supply load, this paper, according to the practical application of high-voltage inverter supply circuit, theoretically analyses and simulates the load impedance＇s change, and finally gives out the simulation curves of the output voltage and current vs the load impedance change. These curves may provide the basis for the design and choice of the system circuit parameters design.
