Abstract :
The authors present the results of EMI tests made on a permanent magnet brushless DC actuator designed for an automotive application. This actuator is fed by a current control PWM voltage source inverter. The described tests allow the influence of different operation modes on electromagnetic interference to be compared. The use of two types of push-pull drivers with or without control of voltage and current gradients during commutation times, the use of two current regulation types with constant frequency chopping or hysteresis control and use of two modulation ways by means of either one or two chopping transistors
