Application of Parallel Active Filter for the Electric Vehicle AC Charge Spots

Currently, many countries are seeking to develop new energy vehicles. AC charge spots are the major energy supply facilities for family electric vehicle, which use the on-board charger. However, due to the non-linear character of on-board charger, the harmonic current will be injected into the grid, and will affect the grid quality within the large scale charge. This paper explores that the active power filter is applied to the AC charge spots, in order to suppress the harmonics of on-board charger which directly interferes with power grids. Applying to two different non-linear loads, the experimental prototype of the single-phase parallel active filter and the composite control method can effectively restrain the harmonics of the on-board charger in order to improve the charging efficiency.
