多模块并联型高压直流电子负载功率控制电路设计
Design of Multi-module Parallel High-voltage DC Electronic Load Power Control Circuit
摘要
Abstract
To meet the test requirements of new energy vehicle batteries,the multi-module parallel method was used to design a high-voltage direct current(DC)electronic load power control circuit.The circuits with constant voltage control,constant current control,constant resistance control,voltage ac-quisition,current acquisition,overvoltage and undervoltage protection,and button displays were de-signed.The circuit parameters were determined through Multisim software simulation,and a printed cir-cuit board was generated.The designed control circuit was tested,and the experimental results show that the voltage of the DC electronic load control circuit is adjustable in the range of 3-600 V,and the relative error is 0.23%.The current is adjustable in the range of 0-50 A,and the relative error is 0.28%.The whole system has good heat dissipation conditions and can stably operate.关键词
