The use of electronic ballast and switching mode power supply in energy conservation has caused power quality problems and less reliable output voltage. Power factor correction (PFC) converters and output voltage are conventionally regulated using the PID controller to condense the current harmonics, increase the power factor and regulate the system output voltage. In general, their output is not very appropriate for non-linear systems. Because this approach is highly non-linear, the PID controller gain optimized in this paper using the grey wolf optimization algorithm to increase the power factor and boost the stability of the AC to DC process output voltage. The simulation studies to demonstrate the efficacy of the proposed grey wolf optimized PID controller is performed in MATLAB Simulink to achieving balanced performance and high power factor.

“…Even though several digital control implementations for PFC converters operated in CCM, DCM or mixed conduction mode (MCM) have already been published [20][21][22][23][24][25], according to the authors' best knowledge no clear controller design and tuning procedures are present in the literature. Moreover, all found solutions are characterized by substantial shortcomings, either being unable to provide constant controller bandwidth (i.e., due to the variable system gain) [20,[23][24][25], or completely relying on the accuracy of simplified system models (i.e., model-predictive control), yielding steady-state and/or tracking errors [21,22]. Although in [20] the feed-forward term is changed at the transition between CCM and DCM operating modes, the PI controller parameters are kept constant, thus resulting in a very low control bandwidth in DCM operation.…”

“…To tackle this issue, Ref. [25] proposes a step change of the controller gain between CCM and DCM operation; however, the DCM gain value is kept constant (i.e., yielding variable bandwidth) and no controller tuning procedure is provided. In particular, none of the mentioned works deals with a PFC operated in DCM over the complete operating range, since single-phase PFC circuits are most often designed to operate either in CCM, MCM or DCM depending on the load current.…”

Full Digital Control of an All-Si On-Board Charger Operating in Discontinuous Conduction Mode

This paper deals with the design, tuning and implementation of a digital controller for an all-Si electric vehicle (EV) on-board battery charger operated in discontinuous conduction mode (DCM). This charger consists of two cascaded conversion stages: a front-end power factor corrector (PFC) with two interleaved legs and an isolated phase-shifted full bridge DC/DC converter. Both stages operate in DCM over the complete battery charging power range, allowing lower inductance values for both the PFC and the DC/DC filtering elements. Moreover, DCM operation ensures a large reduction of the reverse-recovery losses in the power diodes, enabling the adoption of relatively cheap Si devices. The main goal of the work is to address the well-known DCM control challenges, leveraging a novel control strategy for both converter stages. This control scheme counteracts the DCM system non-linearities with a proper feed-forward contribution and an open-loop gain adjustment, ensuring consistent dynamical performance over the complete operating range. The designed controllers are tuned analytically, taking into account the delay components related to the digital implementation. Finally, the proposed control strategy is implemented on a single general purpose microcontroller unit (MCU) and its performance is experimentally validated on a 3.3 kW battery charger prototype.
