Abstract
Uninterruptible Power Supply (UPS) can provide a stable, continuous and uninterrupted power supply and it has higher requirements for the power supply quality of UPS. In order to improve the reliability and engineering feasibility of uninterruptible power supply (UPS) redundant parallel operation system, a phase locking control method is proposed. This method adjusts the AC output by measuring the system frequency dynamics in real time to realize the seamless switching of the bypass input. There is no discontinuous process in this process, so as to provide stable, continuous and uninterrupted power.
