The government requires the full replacement of the rectifier/inverter system located in building 730, room 132. Power rectification is the process of converting an alternating current (AC) waveform into a direct current (DC) waveform, which is essential for powering electronic devices that require a stable, single-polarity power supply. This system hosts power feeds from commercial power, generator power and uninterruptable power supplies (batteries) to ensure steady reliable power for the DoW long haul communications.
