Abstract |
The three-phase buck-boost DC-AC inverter generates three alternating output voltages as the differential voltage of three DC-DC individual buck-boost converters. Three converters are driven with three DC-biased and 1200 phase-shifted sinusoidal references. The peak value of the inverter alternating output voltage can be larger or smaller than the value of the direct input voltage. In this paper, a three-phase buck-boost DC-AC inverter is designed and implemented on a prototype with digital controller using a microcontroller. |
