Design of the Control Circuit of Electric Chassis Vehicle Based on Intelligent Circuit Breaker of IPM Modul
In order to meet the development trend of intelligent circuit breaker
the circuit breaker based on L292 and IPM module and the bipolar H bridge motor drive control circuit for electric chassis vehicle are developed.The principle diagram of control circuit of motor H bipolar reversible PWM electric chassis vehicle driving system is designed in this paper. Experiment results show that electrically operated
working current monitoring and current limiting protection function are realized by this control circuit
it can reduce the labour intensity of operators greatly and improve the stability of control function. Through monitoring the motor current of electric chassis vehicle
the state of the electric chassis vehicle can be obtained in real time and the reliability of medium voltage switchgear can be increased.
