How a Communication Inverter Works and Its Integration with UPS, STS, Switch Power, and Batteries

A communication inverter converts DC power (from batteries) into stable AC power for critical loads. Its working principle involves:
1. DC-AC Conversion: Using PWM (Pulse Width Modulation) and IGBT transistors, it transforms 48V/24V DC into 220V/110V AC.
2. Voltage Stabilization: Filters and regulators ensure clean, sine-wave output.
3. Synchronization: Aligns frequency/phase with grid or UPS for seamless switching.

Integration in a Rack:
- Batteries supply DC power during outages.
- The inverter feeds AC power to connected devices.
- A UPS provides backup and filters power fluctuations.
- A STS (Статик дамжуулалт шилжүүлэгч) switches between grid/inverter power without interruption.
- Switch power supplies** charge batteries and power DC systems.
