A high-voltage DC/DC converter of grounding fault locator which used in distribution network is designed in this paper. The high-out voltage could be a great danger to the operator as the converter is directly connected to the grid. A remote controller of the fault locator which based on wireless communication module PTR8000 is designed. It is used to control the converter remotely and to display the working status and measurement data in real time. Both the remote controller and the converter are working in half-duplex mode. AT89LP3240 microcontroller is the main control chip of the remote controller which can control the communication module, the display LCM and the keyboard. DSP TMS320F2810 is the main control chip of the converter which can control the high-voltage converter and the wireless communication module.
