Design of Charge Point Based on Rectangular Self Convolution Window Algorithm Data Measurement

The charge point design based on the rectangular self convolution window algorithm data measurement is to use the rectangular self convolution window to measure the electric field strength in a certain area. This method can simultaneously measure electric field strength, voltage and current. The main advantage of this method is that it can be applied to any type of charging equipment at any location without changing its form or structure. In addition, the method has no effect on the charging system itself; Therefore, it can be used to test different types of charging systems. In this paper, the main circuit units of electric vehicle charging pile are designed, including rectifier unit, power conversion unit and human-computer interaction unit, and the rectifier unit and power conversion unit are modeled. For the rectifier unit, VIENNA rectifier is used to replace the common power frequency rectifier to provide DC with good power quality. Then DC-DC full bridge power conversion is performed on the output DC current, and the output is adjusted by phase shifting control. Finally, the human-computer interaction unit is designed, and the work flow chart of the human-computer interaction system is given.
