AbstractThe paper introduces a transformerless four-wire power-factor-corrected boost rectifier which does not draw low-order harmonic currents from the supply neutral. The four-wire rectifier topology and control is described. The main application of such a rectifier is a new transformerless, four-wire AC-DC-AC converter for uninterruptible power supplies. Simulation results show the steady-state and dynamic response of the four-wire rectifier and the four-wire AC-DC-AC converter
