Abstract |
|
The primary function of the gate drive circuit is to convert logic level control signals into the appropriate voltage and current for efficient, reliable, switching of the IGBT module. An output driver stage consisting of small power MOSFETs or bipolar transistors convert the logic levels by alternately connecting the IGBT's gate to the appropriate on and off voltages (VON and VOFF, respectively). Most gate drive circuits also isolate the low level logic signals from the dangerous high voltage present in the power circuit. In this paper, V/f control principle is summarized and simple IGBT gate drive circuit with over-current protection is proposed with frequency control module and rectifier bridge module to implement of V/f drive for induction motor. Driver circuit test results are shown. |
