This paper presents a dual-loop control strategy for parallel interleaved three-phase four-leg PWM boost-type rectifier in double conversion UPS. The interleaving method is adopted for its main benefit of harmonic cancellation. The current in the fourth leg is treated as a perturbation because the fourth leg is shared by rectifier and inverter, and the controller can be designed in a-b-c coordinate conveniently. The DCbus voltage feedback in outer control loop can be delayed by quarter-cycle to filter out the oscillating component when the load of UPS is unbalanced. The performance of proposed control scheme is verified by experimental results.
