Dynamic response of boost power factor correction (PFC) converter operating in continuous-conduction mode (CCM) is heavily influenced by low-bandwidth of voltage control loop. A novel tri-state boost PFC converter operating in pseudo-continuous-conduction mode (PCCM) is proposed in this paper. An additional degree of control-freedom introduced by a freewheeling switching control interval helps to...
A model for supercapacitor voltage equalization strategy is analyzed, and on this basis a supercapacitor voltage equalization method for rubber tyred gantry crane (RTG) energy saving system is proposed, namely active voltage equalization method based on buck-boost converter. The equalizing speed of the proposed method is fast. Firstly, the working principle and process of the voltage equalization...
This paper deals with a boost converter for low input voltages in battery or photovoltaic applications. The performance of a dual interleaved boost converter is investigated theoretically and experimentally. In order to increase the power density and to avoid EMI problems caused by the reverse recovery current of the diode, the discontinuous mode is considered only. At first, the steady state performance...
