Prophi® PFC Controller - Janitza Electronics - #1

t Optimised control for long PFC system lifespan The Prophi® power factor controller has an optimised control mode. The implemented control algorithms reduces the number of switching cycles as well as the operating time per capacitor stage. The aim is to have the same number of switching cycles and, if possible, the same operating time per capacitor stage. In addition, the number of switching cycles is reduced by up to 80%. The lifespan of the entire system can be significantly increased through even loading of all stages with an automatically regulated PFC system. This means that invested capital earns money for a longer time period and that new investments can be avoided. The hybrid switching (i.e. the combination of capacitor contactors and dynamic thyristor modules for contact-free rapid switching of capacitors) combines the advantages of rapid switching without network perturbation with the cost advantages of common PFC systems. 102 PQS - Power Quality Solutions Prophi® power factor controller
