摘　　要：研究并设计了一种新型的基于移相全桥PWM控制的数字化臭氧电源。采用频率跟踪技术跟踪负载电流的变化,使电源工作在准谐振状态,采用LPC2129的PWM控制器实现了移相PWM功率调节。实验结果表明,系统运行更稳定,更可靠。此外,还实现了电源控制的数字化。Based on phase-shifted fuU-bridge PWM control, a novel digital power supply of ozonizer was researched and designed.The frequency tracing technique of the load current ensures the power supply of ozonizer to worke at the approximate resonance status.The PWM Controller of LPC2129 realizes power modulation by the phase-shifted PWM technique.The experiment result shows that the system runs more steadily and more reliably, and realizes the digital control.
