Electric vehicle converter

Introduction

The Electric Vehicle Converter serves as the “energy bridge” in EVs, converting high-voltage DC (300V–800V) from the traction battery into low-voltage DC (12V/24V) for onboard equipment such as vehicle lights, infotainment systems, and control units.   Some advanced converters also provide DC-AC conversion, enabling reverse discharge for vehicle-to-load (V2L) applications, such as powering air conditioners or external charging devices.

Key Types

• DC-DC Converters – the mainstream solution, supplying low-voltage systems with stable power.

• Integrated Converters – combining DC-DC with OBC (On-Board Charger) functionality to form “two-in-one” or “multi-in-one” compact modules, saving space and cost.

Core Requirements

• High Efficiency – ≥90% power conversion efficiency reduces energy loss and extends driving range.

• High Stability – robust performance under temperature fluctuations, vibration, and harsh driving conditions.

• Compact Design – miniaturized modules compatible with EV interior layouts.
