FIELD: power supply system.
SUBSTANCE: voltage converter for a hydrogen power supply system for a vehicle. The converter consists of: housing, controller, load switch, precharge resistor, reactor, current sensor, IGBT module, buffer capacity, fuse and diodes. A current sensor and a diode are connected to the reactor output. A buffer capacity at the output and a diode are connected to the IGBT module. The current sensor is used to monitor the output voltage. A fuse link is installed before the output of the voltage converter as a safety device. The voltage converter controller is connected to a control system formed by control boards. Information from the fuel cells is collected on the main control board. An IGBT driver is connected to the voltage converter controller, with the help of which the IGBT module of the boost DC/DC voltage converter is controlled.
EFFECT: powering the vehicle systems while simultaneously charging the battery is achieved.
