| Abstract |
Three-phase AC-AC series-resonant converters with power-pulse modulation and internal frequencies of 10 kHz, suited for multi-kilowatt power levels, have excellent characteristics like the generating of multiphase bipolar waveforms with reversible power flow, low distortion and fast system response. An alternative circuit configuration for the series-resonant AC-AC converter with only 12 thyristors has been presented recently. This paper presents a method to control the source currents to decrease the harmonic distortion and control the power factor of the converter. Simulation results indicate that the harmonic distortion of the first nine harmonics of the source current is reduced from 24.5 % to 2.2 %. The power factor of the converter 's source current is controllable between 1.0 and 0.1, leading and lagging as well. |
