Brogen, a leading provider of customizable EV solutions for commercial vehicles, has launched a (H)EV Auxiliary Inverter for Bus / LCV / HCV applications. This 4-in-1 Auxiliary Inverter comprises a DC/DC converter, two DC/AC converters, and a high-voltage power distribution unit (PDU). Each component serves a critical function in managing the power dynamics of electric vehicles.

The DC/DC converter is responsible for transforming the high voltage from the battery into low voltage. This facilitates the charging of the onboard battery while supplying a steady DC power source to low-voltage components.

The DC/AC converters convert the high-voltage battery’s direct current into three-phase alternating current. This conversion is essential for controlling vital vehicle systems such as the electric air compressor and power steering pump, ensuring the operation of air pressure and power steering functionalities.

The PDU serves as a control hub for the vehicle’s power supply system. It manages tasks such as power distribution, current measurement, short circuit protection, charge and discharge control, pre-charging, manual emergency stop, and insulation detection.
