- Abstract
The main objective of this paper is to present analysis and performance evaluation of averaged current controller for bidirectional DC-DC converters. Two control strategies will be discussed and evaluated: the unified current controller and the separated buck/boost mode current controller or well known as logic-based current control strategy. The feedback current controller designed in this work is a conventional proportional-integral with a feedforward control strategy. The investigation of the control system performance is carried out based on the voltage conversion ratio between the high and low-voltage side of the converter (VH/VL). Based on the simulation studies, the control performance is relatively the same for the small voltage conversion ratios, whereas for the large voltage conversion ratios, the logic-based current control strategy appears to be superior compared to the unified current controller.
