One-cycle controlled active rectifier for full digital implementation

This paper presents a discrete implementation of a Triangular One Cycle Control for three phase active rectifiers. The algorithm is characterised by triangular modulation carrier and can be implementated using a programmable logic device, thus obtaining increased feasibility and performance over analog OCCs systems. Simulation results and comparisons with another three-phase active rectifier control method show that the proposed MT-OCC offers satisfactory performance in terms of high power factor control, low harmonic pollution, fast and accurate dc output voltage regulation and high stability during regenerative operations.
