Title:
TWO-INPUT UNINTERRUPTIBLE VOLTAGE CONVERTING DEVICE AND METHOD THEREOF.
Document Type and Number:
WIPO Patent Application WO/2011/147091
Kind Code:
A1
Abstract:
a two-input uninterruptible voltage converting device and a method thereof. The device comprises: a first converting circuit(100), a second converting circuit(200), an energy storage unit(300), a free-wheel switch(Q5) and a control unit(400). The method includes: converting PWM signals outputted from a pulse width modulator(1) into first, second, third and fourth PWM signals in phase with a pulse transformer(Td); driving the first converting circuit and the second converting circuit respectively to operate synchronously; converting a high voltage DC and a low voltage DC into two pulse voltages in phase to adaptively perform mutual power compensation via a crosspoint; and supplying a load with an uninterruptible stable voltage via the energy storage unit and the free-wheel circuit in the later stage. The circuit of the two-input uninterruptible voltage converting device has high converting efficiency, high reliability and low power consumption.
