Reactive power control by use of boost critical conduction mode power factor correction converter for suppressing voltage rise in distribution network

The authors have proposed a reactive power control method by use of boost critical conduction mode (CRM) power factor correction (PFC) converters to suppress voltage rise in distribution networks. Using this method, PFC converters can control not only inductive reactive power but also capacitive reactive power. Therefore, this method is useful to control voltage. In this paper, a PFC converter and a controller which realizes the proposed method is made to verify the reactive power control ability. The theoretical ratio between reactive and active power is in good agreement with the experimental results.
