SiC power module TH20GT7550C7-WT

BiDi ACDC

Product brief
The TH20GT7550C7-WT is a bidirectional AC/DC charging/discharging module for vehicle-to-grid (V2G) applications. It delivers rated output power of 20 kW, supports DC-side constant-power operation in the 500–750 VDC range and accepts three-phase four-wire AC input (three-phase + PE). The module uses intelligent forced-air cooling and communicates with the main controller via CAN bus for parameter setting and operational control.

Overview
Designed for integration into commercial EV chargers and V2G charging stations, the module provides high efficiency in both AC→DC and DC→AC modes, precise voltage and current regulation, digital address setting with local display and button operation, and low standby power suitable for grid-interactive systems.
