METHOD FOR CONTROLLING A SWITCHING POWER BUCK CONVERTER IN MEDIUM CURRENT MODE Russian patent published in 2022 - IPC G05F1/56 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely to the field of converter electrical engineering, in particular to methods for controlling pulsed power converters, and can be used in methods for organizing power supply for various devices in many fields of technology, for example, in methods for organizing a battery charge on board an aircraft with a hybrid power plant by means of powerful pulse power step-down converters for controlled voltage and current, as well as in methods for organizing secondary power supply of equipment and functional equipment of aircraft with stabilized voltage and current limit value in the load. The effect is achieved by the fact that in the method for controlling a pulse power down converter in the average current mode, including measuring the current in the electrical circuit of the load current in the pulse power down converter, generating a current feedback signal, integrating the current feedback signal, generating a feedback signal by average current, control the average current mode of the pulse power down converter by forced switching between the current and voltage stabilization modes by means of an additionally introduced multiplexer, generated by the resistor, the operational amplifier and the diode, compare the value of the voltage signal proportional to the current in the inductor with the set voltage reference obtained as a result of monitoring the average current mode of the switching power buck converter, control the modulator using the average current signal, and control switching in the switching power down converter from the output of the modulator.

EFFECT: increasing the stability of the battery charging by current while ensuring a high ratio of the power of the converter to its mass and its high efficiency.
