The invention relates to an insulated gate bipolar transistor uninterruptible power supply system, which monitors whether an input power supply is output to a load side swimmingly through a microprocessor, built-in cells are charged through an inverter in a process of inputting a stable power, the input power supply is shadowed when detecting unstable power supply input, DC voltage after being charged is converted to AC voltage through a DC-AC converter, output power supply is provided to the load side in a ceaseless way, thereby protecting working data and stably finishing the system connected to the load side, but the input power supply is still unstable or in a state of power filaure after providing the stable power supply for certain time, the system connected to the load side is forced to close through the microprocessor and an output shadowing unit.
Description
technical field [0001] The present invention relates to an insulated gate bipolar transistor uninterruptible power supply (IGBTUPS: insulated gate bipolar transistor uninterruptible power supply) system, in particular to an insulated gate bipolar transistor uninterruptible power supply system of the present invention that can monitor input through a microprocessor Whether the power supply is smoothly output to the load side. During the input of stable power supply, the built-in battery is charged through the inverter. When an unstable power supply input is detected, the above-mentioned input power supply is blocked, and the charged DC voltage is converted by the DC / AC converter. Convert to AC voltage, supply output power to the load side in a non-instantaneous manner, thereby protecting operating data and stably ending the system connected to the load side, and when the input power is still unstable or remains in a power failure state after supplying a stable power supply for a...
