Typical Battery charger mainly consists of two stages: AC to DC stage employing boost or interleaved boost converter where power factor correction is taken care by employing suitable control technique and boosting voltage level to an intermediate dc bus level. The second stage is DC/DC stage where the voltage is regulated according to the battery requirement and provides the galvanic isolation for...
In this paper, a generalized mathematical model for buck, boost and buck-boost converters is derived. An average power balance control (APBC) scheme is proposed and analyzed for these converters. The proposed scheme consists of two control loops, the fast inner current loop uses sliding mode control (SMC) and outer voltage loop uses the average power balance algorithm (APBA). The existence condition...

This paper proposes a boost inverter topology to realize the reference currents generated by Instantaneous Symmetrical Component theory. The circuit topology and the switching pattern of the boost inverter boosts up a low voltage DC (e.g. photovoltaic panel or fuel cell) of a sustainable energy source to inject the required filter currents. The proposed boost inverter can perform load balancing, harmonic...
