| This paper presents an intelligent high voltage charging power supply for new applications . It is the core and key of electricexplosure cleaning system . This power supply have some advantages, such as small in size , light in weight, easy to operate Low switching loss , low noise , and so on. These advantages benefit from utilizing a new circuit topology construction single chip microcomputer and advanced IGBT intelligent power module combining PWM with resonant converter. This paper introduces in detail the operation principle of main circuit , triggering circuit fault-alarm and protection circuit . Experiment results and some problems which should be noticed in applications are presented. |
