The Supercapacitor-assisted low-dropout (SCALDO) regulator is a unique new DC-DC converter design approach with high end-to-end efficiency (ETEE), where a supercapacitor is used as a lossless voltage dropper in the series path of a linear regulator. This technique, in which the energy recovery happens at a very low frequency (typically in millihertz), with an efficiency multiplication factor in the range of 1.33 to 3, can be used in many different applications. For example, in a 12-5V linear converter where the theoretical maximum efficiency is 41.67%, the SCALDO approach improves it to 83.33%. The SCALDO technique has been extended to multiple useful applications proving its versatility and has been identified as an entirely different approach compared to conventional switched capacitor converters. In this paper, we provide an in-depth discussion on the expansion of the SCALDO technique into a dual-polarity, splitrail DC power supply with high ETEE, high current, high slew-rate capability and other desirable features. It also presents the experimental results for a 12V to ± 5V prototype with steady-state performance, transient response capability, load/line regulation, and loss estimation.

“…As to the switch-resonant converter [7], the converter only uses the resonance generated by resonant elements to provide the voltage or current required for zero voltage or current switching when the switch is switched. Resonant elements only partially participate in the energy conversion process of the converter, which is also called a semi-resonant converter or quasi-resonant converter [8,9].…”

Soft Switching of Non-Isolated Buck-Type Converter with Common-Ground Switch

A non-isolated buck converter, together with resonance and zero voltage transition to achieve zero voltage switching (ZVS) and zero current switching (ZCS), is presented herein to upgrade the conversion efficiency. In this circuit, the main switch and the auxiliary switch are connected to the common ground so as to make the two switches easily driven. Furthermore, these two switches take time division multiplexing operation. In addition, the pulse width modulation (PWM) control technique is utilized so as to render the output inductor and capacitor easily designed. In this paper, the theoretical derivation is first introduced, and secondly, some experimental results are provided to demonstrate the effectiveness of the proposed topology.

State-of-the-Art Review on Soft-Switching Technologies for Non-Isolated DC-DC Converters

et al. 2021

The soft-switching technology is widely used in DC-DC converters, DC-AC inverters, and AC-DC rectifiers. Soft-switching non-isolated DC/DC converters (Buck, Boost, and Buck-Boost) are the most active research area of the soft-switching technology, and fruitful results are achieved. However, there is currently no comprehensive review for the soft-switching technology of non-isolated DC/DC converters. This paper introduces soft-switching topologies for non-isolated DC/DC converters, and presents classification and characteristic of all kinds of soft-switching technologies. Some soft-switching technologies of derivative converters (non-inverting Buck-Boost converters and multiphase converters) are also presented. Finally future trends and generalized constitution methods of the soft-switching topology for non-isolated DC/DC converters are concluded. The soft-switching theory and constitution methods summarized in this article are expected to be able to guide the proposing of new soft-switching technologies for DC-DC converters.
