Rancang Bangun Inverter Multipulsa untuk Beban Penerangan Rumah Tangga Jenis Lampu Pijar

Backup power supply system as an alternative voltage source supply for household expenses at this project is designed to be able to maintain a constant output voltage according to the rating of 220V, when the load changed or input voltage (from accu) decreased. This backup power supply system consisting of battery 24 V, boost converter increase DC voltage to 100V, the inverter changes DC voltage 100V into AC voltage 70V , 70V to 220V step up transformer and ATmega16 microcontroller as PWM generator for boost and inverter and as proportional control intregal ( PI). PI control the ignition IGBT boost converter to regulate output voltage of the system. From the system test, has been designed, the output voltage of the system is only able to 130V, it is because a large drop that occurred on the side of the transformer. So taken with the 125V setpoint value of the controller parameters Kp = 0.5 and Ki = 0015 at the maximum load 100W/220V Keywords: backup power supply, Boost Converters, Inverters multipulsa, Transformers Step Up, Controls P
