FIELD: electricity.
SUBSTANCE: application: in electrical engineering. Uninterrupted power supply system consists of a rectifier comprising a transistor and induction coil, a controller, current sensor, the first and second transistors forming a part of the scheme for the first and second buck converters respectively.
EFFECT: controller is capable of delivery of the first and second control signals of pulse-width modulation to the first and second transistors respectively in order to switch operation mode of the first and second buck converters respectively from intermitted duty at variable frequency and continuous duty at constant frequency.
