Abstract

Electrical energy system now is an important asset in daily life so the use of electrical power or converter are common. Converter are usually divide into converter current source and converter voltage source. Converter needs an analog or a digital trigger signal to make it work. This kind of triggering keeps on developing of using microcontroller to change the analog trigger signal to stabilize the wave output. DsPIC30f4011 is a microcontroller having special features to support the three-phase UPWM signal generation including dead time setting, complementary modes and center aligned mode. In this study, three-phase full bridge inverter with UPWM switching technique microcontroller dsPIC30f4011 was designed and implemented. The carrier signal was set 10 kHz with modulation index (ma) 0 ≤ ma ≤ 1, and the reference signal frequency was 0 - 50Hz. The experimental results showed that PWM signal generated by microcontroller matched with UPWM characteristic. The measured, line to line output voltage waveforms of the inverter were almost sinusoidal and the waveform can be varied linearly according to the modulation index in the range of 0 ≤ ma ≤ 1 with frequency range in 0-50 Hz. Finally, line voltage unbalance ratio( LVUR) and current unbalance ratio (IUR) generated by the propossed circuit. Keywords: Inverter full bridge, UPWM, dsPIC30f4011, LVUR, IUR.
