UPS power supply How it works:




1. AC-DC conversion: The power of alternating current through the autotransformer to buck, full-wave rectifier, filtered into a DC voltage supply power inverter circuit. AC-DC input with soft-start circuit can avoid the boot of the grid impact.



2. DC-AC power inverter circuit: Using high-power IGBT module full-bridge inverter circuit, has great power surplus capacity in the output dynamic range output impedance are very small, with fast response characteristics. As a result of limiting high-frequency modulation techniques, and rapid short-circuit protection technology, so that both the supply voltage inverter or the load transient shocks or short circuit, can be safe and reliable work.



3. Control-driven: Control-driven machine function controlled by the completion of the core, it addition to providing detection, protection, synchronization, and various switches and display drive signals, but also the completion of SPWM sine pulse width modulation control, due to static and dynamic double voltage feedback. Greatly improves the dynamic characteristics of the inverter and stability.



ups using a 12V battery, and it has 2V's. Can use the same voltage battery instead of the market (preferably buy a maintenance-free batteries), but pay attention to the size, can be put to because as of course, is also connected to the outside line, but not pretty!
