SiC-BASED POWER MODULE UTILIZING HIGH-TEMPERATURE GATE DRIVERS WITH OPTICAL FIBER-BASED ISOLATORS

Abstract

A power module that utilizes high-temperature gate drivers with optical fiber-based isolators. The power module includes a gate driver, which includes one or more optical fiber-based isolators configured to provide electrical isolation between low-voltage circuitry and power devices of the power module. Furthermore, the gate driver includes an amplifier configured to enhance a control signal. Additionally, the gate driver includes a gate driver integrated circuit configured to provide voltage and current to drive the power devices of the power module based on the control signal. Furthermore, the gate driver is fabricated on a substrate, such as a low-temperature co-fired ceramic substrate. As a result, the power module with the optical fiber-based isolator allows for a wide range of operation temperatures and fast switching frequency.
