Communication dedicated inverter system working block diagram: As shown in Figure 1

Figure 1 Communication dedicated inverter system architecture block diagram

A. inverter system operates in various parts of the bypass state circuit works: After entering through mains EMI filter to filter out noise interference sent mains end, after sending the static switch via the output EMI filter to remove After the interference to the user load terminals, providing power for the user load. machine output at this time is just after filtering without voltage, frequency stabilization process in the ordinary mains.
