Zhu Long-ji · Colliery Mechanical & Electrical Technology · 2006
The paper analyzes the cause of magnetic biasing occurred in the power frequency transformer of sine wave inverter.The digital PI regulating method is adopted to adjust the width of trigger pulse so as to restrain magnetic biasing.This method is applied and debugged for inverter and its feasibility is proved.
