VOLTAGE CONVERTER Russian patent published in 2021 - IPC H02M3/335 

FIELD: converting tech.

SUBSTANCE: invention relates to the field of converting technology and can be used to power various types of loads, including voltage inverters of DC and AC drives, mainly when powered from a low-voltage source. The main area of application of the device is AC and DC electric drives on moving objects. The technical result is to increase the reliability and expand the functionality of the voltage converter. For this, the claimed voltage converter contains two bridge voltage inverters, two transformers, two rectifiers, a control unit, according to the declared solution additionally introduced with the appropriate connections are: an inclusion unit, an input filter, a voltage sensor, a temperature sensor, a resistor and a drain circuit key, two current sensors, output filter, blower unit, control unit is configured to implement the function of the current and voltage regulator of the converter stages and the algorithm for testing the initial state of the device, while each series-connected corresponding current sensor, bridge voltage inverter, transformer and rectifier form a converter stage, and the number of converter stages included in the voltage converter is determined by the required output power of the voltage converter. In addition, the control unit consists of a key control driver, an amplifier, a sensor signal processing circuit and a control circuit, wherein the first output of the control circuit is connected to the input of the key control driver, the second output is connected to the amplifier input, the first input is connected to the output of the sensor signal processing circuit, and the second input with the "In" converter control terminal.

EFFECT: reliability increased, functionality of a voltage converter expanded.
