Hi All,
A 380V DC power supplier controlled by a 24V PWM singal, to supply a coil. max current 6A.
The pwm pulse is 10-40us.
measured overshoot on the 380V voltage, attached is the waveform picture.
can you help suggest how to improve the overshoot issue, is it a solution to add high voltage film capacitors on the load coil? like Metallized Polypropylene Capacitors (MKP/MFP).
Any comments are appreciated.
