| Abstract: | Based on phase-shifted full-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 experi-ment result shows that the system runs more steadily and more reliably,and realizes the digital control. |
