METHOD FOR CONTROLLING A PULSED POWER CONVERTER IN MEDIUM CURRENT MODE Russian patent published in 2023 - IPC G05F1/56 

FIELD: electrical engineering.

SUBSTANCE: in the control method pulse power converter is in the medium current mode, including the measurement of the current in the electrical circuit of the load current in the pulse power converter, the simultaneous formation of a current feedback signal to an additionally introduced second pulse-width modulator after subtracting a fixed voltage from the current feedback signal by means of an additionally introduced device voltage subtraction, at the output of which control pulses of increasing voltage of the required duty cycle are formed by means of the power circuit of increasing voltage formed by the inductor and additionally introduced second field-effect transistor, second power diode and smoothing capacitor, integration of current feedback signal, formation of average current feedback signal, control of average current mode of switching power converter by forced switching between current stabilization and step-down voltage modes by means of multiplexer formed by resistor, operational amplifier and a power diode, comparing the value of the step-down voltage signal proportional to the current in the inductor, which together with the switching device containing the field-effect transistor, forms the step-down electrical circuit of the pulse power converter, with the set reference voltage value obtained as a result of monitoring the average current mode of the pulse power converter, control of a pulse-width modulator using an average current signal and switching in a pulsed power converter from the output of a pulse-width modulator, forming control pulses of a step-down voltage of the required duty cycle, coming to the gate of the field-effect transistor through the driver.

EFFECT: increasing the stability of the battery charging process both in terms of voltage and current with increased efficiency in a wide range of voltages, conversion factors and power levels of a pulsed power converter while improving the transient response with a sharp change in the operating mode.
