Abstract
FIELD: electric engineering, electric power supply of electronic devices and computers during mains voltage falls. SUBSTANCE: device has charge rectifier 1, which output is connected to redundant power supply 2 and high-frequency inverter 3, which control input is connected through commutator 4 to control unit 5, which sends modulating voltage, for example, by means of pulse series. During single half-period commutator 4 switches supply of modulating voltage between diagonals of bridge of high-frequency inverter 3, which outputs amplified double-polarity series of pulses. Said series is rectified by high-frequency rectifier 6 and is converted to single-polarity pulse voltage by means of smoothing filter 7. This voltage is supplied to input of low-frequency inverter 8, which switching is controlled by control unit 5. This results in output of sine-shaped voltage of 220 V and 50 Hz from low-frequency inverter 8. EFFECT: increased stabilization range, decreased size. 3 cl, 1 dwg
