- Compensation of nonlinear loads with series active power filter and parallel passive filter.
- Proposed of a control strategy for hybrid filter.
- Behavior analysis of a hybrid filter subjected to electromagnetic compatibility test.
In this paper a control strategy for a hybrid filter has been proposed. The hybrid filter consists of an active power filter connected in series with the source and a passive filter connected in parallel with the load. The proposed strategy is based on minimizing the effective value of the voltage at the point of common coupling to ensure the transfer of the power demanded by the load. By applying the Lagrange multipliers, the value of the equivalent resistance of the set load-compensator was determined in order to achieve unity power factor. An experimental prototype was designed to verify its behavior. The compensation equipment operation was analyzed from the point of view of the system stability and from their behavior regarding disturbances of the grid voltage. For this, the hybrid filter was subjected to six electromagnetic compatibility test as it is defined in IEC 61000 standard. In all tests, the equipment maintained its functionality before, during and after the perturbation in the supply voltage.
