400–850V On-Board High-Voltage Converter

Voltage Conversion Capability: Converts the power battery pack (400V-850V DC) into 220V/380V AC power, meeting the electrical requirements for vehicle lighting, instrumentation, BMS systems, navigation, audio, air conditioning, and external appliances.

Operating Principle and Control: Employing SPWM pulse width modulation control technology, the DC-AC converter generates a sine wave via full-bridge inversion and filtering. Optimised control algorithms enhance dynamic response, incorporating overvoltage/overcurrent/overheat/short-circuit protection alongside CAN/RS485 communication interfaces.

Technical Features: Efficiency reaches 90%-93%, featuring high power density and modular design. Wide voltage adaptation (400-800V dynamic range).

Application Scenarios and Value: In new energy vehicle outdoor scenarios, it powers camping appliances and emergency equipment; in traditional fuel vehicles, it replaces the generator for power supply. Its significance lies in ensuring stable equipment operation, extending battery life, and enhancing energy efficiency.

Compact and portable, it fits neatly into the corner of your vehicle without taking up excessive space. Simply connect it to your car's cigarette lighter socket or battery for instant power delivery. Whether charging mobile phones or tablets during long journeys, powering a laptop for work, or supplying electricity to low-power appliances like electric kettles or car refrigerators, it handles the task effortlessly.

The mobile high-voltage converter features multiple safety protections against overload, short circuits, and overheating, ensuring reliable operation. Select models also offer USB ports for direct charging of electronic devices. This device brings home-like convenience to your travels, significantly enhancing your journey experience. It is an essential item for both self-drive enthusiasts and business travellers.
