The powerful pulsed DC-DC converter for charging battery packs on an hybrid and electric aircraft board was constructed. It allows charging the battery during the cruise flight mode of the aircraft. The modular designed 10 kW-converter can operate as in a step-up mode as in a step-down mode in a voltage range of 130 - 300 V with a current limit of 70 A at an output voltage of 150 V. The converter`s efficiency is ~ 96 – 99 % depending on the power consumed in the load. The proposed modular design and the original multiphase control circuit can be used to build converters of different power with high efficiency.
