1. Input filtering: complete the filtering of the input power supply, and provide clean power supply for power dedicated ups.
2. AC / DC boost: AC / DC conversion is conducted for filtered mains power, and boost processing is conducted for DC / AC inverter.
3. DC / DC isolated boost: when the power dedicated UPS works in the battery power supply mode, the circuit carries out DC boost processing for DC / AC inverter.
4. DC / AC inverter: convert the DC power after boost treatment into stable AC output.
5. Bypass: when the inverter has overload, abnormal inverter and other faults, it will automatically switch to the bypass power supply mode to ensure that the load does not power off.
6. Battery: provide uninterrupted power supply energy when the power supply is abnormal.
7. Output filtering: complete the inverter output filtering and provide clean power for the load.

Online working status description:
When the AC input, bypass input, and DC input are all normal, the AC input is isolated and filtered, and then converted into pure AC power through static switch 2 to provide power to the load (i.e. AC inverter power supply).
When the AC input is abnormal and both the bypass input and DC input are normal, the DC is isolated and filtered before being inverted into pure AC power, which is supplied to the load through static switch 2 (i.e. DC inverter power supply);
After the AC input is restored, it will be converted to AC inverter power supply.
When both AC and DC inputs are abnormal and the bypass input is normal, the bypass input provides power to the load through static switch 1 (i.e. AC bypass power supply);
