abstract

• This paper proposes a buck converter with an LC input filter for power factor correction when connected to the grid by means of a non-controller rectifier. The output voltage is regulated to a constant reference by using a conventional controller over the voltage error. This converter may find potential applications, for instance, by supplying a constant voltage to LED based lighting systems and in energy storage applications. In this paper conditions for discontinuous conduction mode operation and theoretical current and voltage waveforms are provided. A voltage regulation controller is also presented along with experimental results which were performed on a low power experimental setup. The controller regulates the output voltage to a given constant reference and discontinuous conduction mode allows the input current envelope to follow the grid voltage waveform. © 2018 IEEE.
