Abstract

To reduce the number of mounted components in the power conversion device and drive device. Each high-side transistor and low-side transistor has an EGE-type structure of (emitter-gate-emitter type). A high-side driver includes a first pull-up transistor configured to apply a first positive voltage to a gate based on an emitter of the high-side transistor, and a first pull-down transistor configured to couple the gate to the emitter. A low-side driver includes a second pull-up transistor configured to apply a second positive voltage to the gate based on an emitter of the low-side transistor, and a second pull-down transistor configured to couple the gate to the emitter.
