FIELD: engineering of devices for transforming direct voltage to alternating voltage.
SUBSTANCE: proposed is saturation inverter with protection of transformer from one-sided saturation, with stabilization of active value of output voltage. Force transformer is utilized, primary winding of which is formed by two serially connected windings with their splitting from point of their connection. For turn-wise connection of windings to source of power, commutators are installed. Frequency of output voltage of inverter is set by clock generator. Two channels are present for measuring voltage induced in windings of first and second semi-periods. When in one of windings one semi-period is formed, another winding is utilized at that time as measuring winding, on which current voltage, proportional to EMF of transformer core magnetization, is measured.
EFFECT: prevented one-sided saturation of force transformer of inverter and simplification of construction of device.
