    ABSTRACT The use of non linear loads such as VSD cause a large harmonics. Because of the harmonic actually need to reduction the spectrum of harmonic by installation of passive filters. Power on the filter inductor can be utilized as a source of energy by replacing the inductor into the transformer. Rectified secondary side and raised using a full bridge DC-DC converter is then converted using an inverter in the hope of a new alternative energy sources. Utilization is limited by the power from filter transformers only, so do not pay attention the harmonic currents. Full bridge DC-DC converter using phase-shifted method on its DC voltage regulation. While the inverter using the Sinusoidal Pulse Width Modulation (SPWM) method. In planning consists of a battery 36 V, full bridge DC-DC converter as step up DC voltage into 300V, inverter changes 300V DC voltage into 220V AC, and the microcontroller ATmega16 as a pulse generator PWM and SPWM. In testing the entire system, with load variation (170 watts) is capable of producing 200 volts AC voltage with a current 0.7 A. Then, after integration with the filter transformer, resulting voltage is 150 volts AC with a load of 18.4 watts. And THDi system changed from 85.3% to 52.89%. When the load is increased to 300 watts, the inverter output voltage drop. Thus the design of full bridge DC-DC converter is less able to meet the planning of power 450 VA. Keywords: Alternative energy sources, passive filters, full bridge DC-DC converter, SPWM inverter
