Advance battery charger topology using SPMC incorporating active power filter

This paper presents the application of single-phase matrix converter (SPMC) as a single-phase AC-DC controlled rectifier incorporating active power filter as a battery charger. The output voltage of the charger should deliver a clean regulated voltage output with sinusoidal input current. A current control loop (CCL) using standard proportional integral control was used to correct the pulsating nature of the input current to almost unity power factor form with low total harmonic distortion (THD) level well below the acceptable limit that was defined in the standards of IEEE 519. Prior to its practical realization a computer simulation model is developed to investigate the behavior of the SPMC to the charging characteristic of lead-acid and lithium-ion battery using MATLAB/Simulink (MLS). Selected simulations results was presented to verify proposed operation.
