In this paper, a buck resonant voltage divider (BRVD) with bidirectional operation considered is presented with the fixed switching frequency all over the load range, which can be used as the first stage of the bus converter. The proposed buck resonant voltage divider with open loop control can obtain about half of the output voltage created from the resonant voltage divider. Above all, all switches...
In this paper, a main circuit, a buck converter, together with an auxiliary circuit, bidirectional buck converter, is used to charge two Li batteries connected in series. By doing so, such an auxiliary circuit takes two roles in executing equalization between the two Li batteries. One role, together with the main circuit, to charge the second battery whose low-level terminal is connected to the ground...
In this paper, the soft switching technique is applied to the KY converter to upgrade the efficiency in the neighborhood of the rated load and hence enhance its capability in industrial applications. The details of soft switching of the KY converter are illustrated along with some simulated and experimental results to verify the effectiveness of the proposed control scheme.
In this paper, a novel dual-output boost converter with positive and negative output voltages under a single positive voltage source fed. Due to its dual output with positive and negative output voltages, this converter is very suitable for driving the half-bridge class-D amplifier, so as to remove a blocking capacitor required in the half-bridge class-D amplifier. Firstly, the basic operating principles...

In this paper, a novel step-up converter is presented, where the charge pump concept, combined with the traditional boost converter structure, is utilized. Although two inductors are used in such a converter, the difference in value between the two inductors does not degrade the performance of this converter. Besides, the behavior of this converter is similar to the traditional boost converter, and...
In this paper, a two-stage boost converter is presented, which is the derivative three-level boost converter cascaded with the KY converter. Such a converter has continuous input and output inductor currents in the continuous conduction mode (CCM), different from the traditional boost converter. And hence, this converter is very suitable for low-ripple applications. The detailed illustration of the...
