FIELD: electrical equipment.
SUBSTANCE: invention relates to the electrical equipment. For this, the following functional units can be distinguished in the proposed device: 1. Control unit. Provides cyclical, alternate supply of control impulses of duration TI = T / n with a predetermined period T, which control the opening of electronic power switches located in the switching unit; 2. Switching unit with a group of logic elements. It provides connection using power tongs to the output terminals of the switching unit of the voltage sources generated by the power supply unit. Group of logical elements OR, located in the switching unit, allows to reduce the number of power switches in two (or more) times; 3. Power supply unit includes a set of constant voltage sources of a given value. Each voltage source in the sequence specified by the control unit is connected for a time interval by TI tongs located in the switching unit to the output terminals of the switching unit.
EFFECT: technical result characterizes a decrease in dimensions and weight of the device, an increase in energy characteristics due to a reduction in losses in power switches thereof, and an increase in reliability.
