Abstract
In this paper, a systematic overview of PLL-based closed-loop control methods for interleaved DCM/CCM boundary boost PFC converters is presented. It is shown that the PLL-based closed-loop methods always provide stable operation, unlike the open-loop control methods, where the only method which results in stable operation is the slave synchronization to the turn-on instant of the master with current-mode control. It is also shown that the dynamic response of the PLL-based closed-loop methods with master-slave approach and dem ....etc

Abstract
A new zero-voltage-switching (ZVS) control approachis presented for pulsewidth modulation (PWM) buck convertersunder discontinuous conduction mode (DCM)/continuousconduction mode (CCM) boundary. This proposed technique compensatesfor control circuit delay, and hence, turns on power MOSat the instant exactly when drain-to-source voltage becomes zero.No complicated timing calculation circuits or additional externalcomponents are required. This proposed integrated ZVS controlcan be applied to other dc–dc converters as well. The ....etc

Abstract—

This paper proposes a new soft-switched continuousconduction- mode (CCM) boost converter suitable for high-power applications such as power factor correction, hybrid electric vehicles, and fuel cell power conversion systems. The proposed converter achieves zero-voltage-switched (ZVS) turn-on of active switches in CCM and zero-current-switched turn-off of diodes leading to negligible reverse-recovery loss. The components’ voltage ratings and energy volumes of passive components of the proposed converter are greatly reduce ....etc

A Multiple-Input Dc-Dc Positive Buck-Boost Converter Topology

Abstract-
A new multiple-input hybrid energy conversion topology is presented. The proposed topology is capable of combining different energy sources with different voltage-current characteristics, while achieving low part number and bi-directional operational. Compare to previous multiple-input buck-boost converter, the proposed topology provides positive output voltage; it is capable of bi-directional operation; and it has the capability of operating in buck, boost, and buc ....etc

DC−DC Buck/Boost Converter
Buck/Boost converter
This circuit is more unforgiving than the boost converter, because the MOSFET and diode voltages and currents are higher
• Before applying power, make sure that your D is at the minimum, and that a load is solidly connected
• Limit your output voltage to 90V
KVL and KCL in the average sense
Interestingly, no average current passes from the source side, through C1, to the load side, and yet this is a “DC - DC” converter
Inductor L1 current ratin ....etc
