Abstract:
Electricity is the main requirement nowadays, but blackouts still occur frequently, this is caused by several things, one of which is the transmission and distribution disorders, especially when it rains badly. Some houses use backup resources such as generator sets that operated during a blackout. This research proposes a temporary backup resource source that is Uninterruptible power supply (UPS) , by using fullbridge inverter with battery 12 volts as a source. This system using Solid State Relay (SSR) as switch so the displacement switches between PLN and the UPS has no delay time. Inverter using SPWM switching techniques to produce a sinusoidal wave output approaching. There is a proportional integrator (PI) control to maintain the value of the inverter output voltage by changing the value of magnitude amplitude (ma). The results obtained that the UPS can work in the event of a blackout with a maximum power of 450 watts, by maintaining the output voltage in 215 V with PI control.
