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

Цель изобретения - обеспечение бесперебойного питания в широком диапазоне стабилизации выходного напряжение при одновременном снижении габаритов устройства. Это достигается тем,что в предлагаемом устройстве, содержащем зарядный выпрямитель 1, к выходу которого подключен резервный источник питания 2 и высокочастотный инвертор 3, на управляющий вход которого от блока управления 5 подается модулирующее напряжение, например, в виде импульсной последовательности, через коммутатор 4 обеспечивающий подачу модулирующего напряжения поочередно в пределах одного полупериода выходного напряжения то на одну, то на другую диагонали моста высокочастотного инвертора 3. Формируемая на его выходе усиленная двуполярная последовательность импульсов выпрямляется высокачастотным выпрямителем 6 и с помощью сглаживающего фильтра 7 преобразуется в однополярное пульсирующее напряжение, подаваемое на вход низкочастотного инвертора 8, коммутация которого блоком управления 5 обеспечивает получение на выходе низкочастотного инвертора 8 синусоидального напряжения 220 В с частотой 50 Гц.The purpose of the invention is the provision of uninterrupted power in a wide range of stabilization of the output voltage while reducing the size of the device. This is achieved by the fact that in the proposed device containing a charging rectifier 1, the output of which is connected to a backup power supply 2 and a high-frequency inverter 3, the control input of which is supplied from the control unit 5 by a modulating voltage, for example, in the form of a pulse sequence, through a switch 4 providing the supply of the modulating voltage alternately within one half-cycle of the output voltage, then on one, then on the other the diagonal of the bridge of the high-frequency inverter 3. The amplified formed at its output vupolyarnaya pulse sequence rectified vysokachastotnym rectifier 6 and 7 through the smoothing filter is converted to a unipolar pulsed voltage applied to the baseband input of the inverter 8, switching control unit 5 which produces at the output of the low frequency inverter 8 sinusoidal voltage of 220 V with a frequency of 50 Hz.
