基于DSP的高频高压交流电源的优化

针对市场上大多数等离子电源,功率因数低、可控性差等缺点，介绍了一种基于DSP的高频高压交流电源。首先介绍电路的设计，其次分析了比例谐振（PR）控制算法，针对PR算法的不足，提出了准PR控制算法，并介绍了准PR的实现过程。为了验证该控制策略的正确性，采用介质阻挡放电管,搭建实验平台进行了对比实验，实验验证了想法的正确性。

Optimization of High Frequency and High Voltage AC Power Supply based on DSP

In view of shortcomings of most plasma power supply on the market, such as low power factor and poor control ability, a high-frequency and high-voltage AC power supply based on DSP is introduced. Firstly, the design of the circuit is introduced. Then, the PR control algorithm is analyzed. In view of the shortage of the PR algorithm, a quasi-PR control algorithm is proposed and the realizing process of quasi-PR is introduced. In order to verify the correctness of the control strategy,an experimental platform for comparison was built by using the dielectric barrier discharge tube. The experiment verified the correctness of the idea.
