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
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

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

A buck“boost transformer is a autotransformer used to make small adjustments to the voltage applied to alternating current equipment. Buck“boost connections are used in several places such as un interruptible power supply (UPS) units for computers in the tanning bed industry. Operating electrical equipment at other than its designed voltage may result in poor performance, short operating life, or possibly overheating and damage.For large adjustments in voltage (more than 15% to 20%), usually a two-winding transformer is used with t ....etc
