The controller identifies the power of the connected capacitor stages and connects or disconnects them in an optimized manner as required by the actual mains conditions. The regulation considers the frequency of changes in the reactive load and follows the principle of rotational switching. This guarantees that optimum power factor correction is achieved with the minimum number of switching operations.
