Abstract :
The paper analyzed in detail the operation principle, mathematical modes and distinct control manner using synchronous reference frame (SRF) of a three-phase series-parallel double conversion UPS system. The proposed control strategy can make this kind of UPS carry out all of the control goals: sinusoidal input current with unit power factor and sinusoidal output voltage with normal value in the case of non-sinusoidal, non-normal supply voltage and non-linear load with reactive power.
