This paper presents and describes the design and implementation of a new gate driver circuit for a three-phase grid tide photovoltaic inverter system using SIC- MOSFET at the power stage. The proposed design consists of a 5 kW power three-phase inverter system with a new isolated gate driver related to IGBT, MOSFET and SIC-MOSFETs. The designed circuit has a dual gate driver in a single package for each leg, and each circuit has an optocoupler to provide high output peak current to turn the power transistor On or Off, and a saturation protection circuit. The control algorithm for the full system of the three-phase application runs on a TMS320F28335 DSP. The TMS320F28335 Digital Signal Processor (DSP) microcontroller is one of the Texas Instruments™ (TI) family that was used to generate the three-phase 120⁰ Bus Clamp PWM of the system, with high frequency around 25 kHz.
