Published by Dranetz – BMI Case Studies A plastic extrusion manufacturer in the mid-West had a 480V delta feeding a plastic extrusion machine. The ASD-driven synchronous motor in the extruder had a half-wave bridge rectifier circuit to provide excitation voltage to the pole coils. Diodes on the half-wave bridge exciter circuit were blowing out, andContinue reading “Voltage Transients Causing Diode Failures”
