3.7kW Single-Stage Matrix Converter

The single‑stage matrix converter topology serves as a high‑efficiency AC/DC bidirectional converter that eliminates the need for separate front‑end PFC and DC/DC stages typically found in conventional designs. By integrating a primary AC/AC bridge formed with bidirectional devices, a high‑frequency transformer, and a secondary high‑frequency AC‑to‑DC rectifier stage, this architecture minimizes energy conversion losses associated with multistage configurations. The use of bidirectional switch (BDS) GaN devices and a compact high‑frequency transformer enables high power density and efficient operation.

System Benefits:

• Single‑stage AC/DC bidirectional power conversion eliminates the need for PFC inductors and DC bus capacitors.
• High‑frequency transformer isolation enables a compact design with high power density.
• Optimized architecture supports high system reliability and long operational life.
• High‑efficiency power conversion enables improved overall system performance, achieving greater than 97% efficiency at full load using Renesas GaN FETs.
• Low total harmonic distortion (THD) ensures compliance with the latest grid standards for improved power quality.
