摘要: As the matrix converter performs electric energy direct transfer from input to output, distortion and unbalance of voltages affects directly output converter. This paper presents a new simple current control for based on fact that if magnitude space vector is constant, currents are sinusoidal balanced. With this control, it possible compensate under unbalanced distorted voltage conditions without need symmetrical components decomposition or reference frame conversions. So not necessary heavy computation capability hardware implementation very simple. The proposed scheme employs only one PI regulator since modulation applied in switching frequency kept constant
