This paper proposes a non-isolated single-stage high power factor rectifier suitable for applications requiring low-voltage and high-current output. The proposed converter integrates two buck-boost converters with a buck converter. As a result, the proposed converter can operate over a wide range of input voltage with extended low output voltage capability, making it suitable for universal input applications...
This paper proposes a digital predictive current controller applied to a power factor correction boost converter rated to a wide range of output power, operating in mixed conduction mode with fixed switching frequency. The current controller comprises two predictive model based control laws (one for the continuous and another for the discontinuous conduction mode) and an operation mode selection algorithm,...
This paper addresses several issues concerning the modeling and application of single-phase, single switch, power factor corrected AC-DC high frequency switching converter topologies with transformer isolation. A detailed analysis, simulation and development are presented for forward buck and flyback buck-boost converters with high frequency isolation in discontinuous conduction mode (DCM) operation...
In single stage, power factor correction circuits, the high voltage of the bulk capacitor is a common problem. This paper analyses the reason for this problem and then proposes a novel boundary conduction mode (BCM) of PFC circuit to solve the problem. Based on the analysis of the boundary point of the PFC converter and the DC-DC converter, the analytic formulation of the working principle of the...
