Considering that the drive circuit wirings and the circuit are complex in IGBT/MOS transistor drive circuit, due to its circuit isolation and auxiliary power supply being implemented by the separated circuits, this paper designs a novel carrier drive circuit using the conventional devices, gives out its configuration, analyzes its operating principles and also verifies its feasibility. This designed drive circuit achieves the energy transfer and signal transmission while the circuit is not limited by the operating frequency and duty ratio.
