The proposed zero-current switching switched-capacitor (ZCS SC) DC-DC converter is an innovative bi-directional power flow control conversion scheme. A zero-current switching switched-capacitor stepup/step-down bi-directional converter is presented that can improve the current stress problem during bi-directional power flow control processing. It can provide a high voltage conversion ratio of n...

This paper studies the “intermittent” chaos and subharmonics observed in switching dc/dc converters using a simple circuit model that describes possible unintended coupling of some weak spurious signal to the converter. The study shows that the signal strength and frequency of the intruding signal are vital parameters that affect the type of intermittent behavior and the period of intermittency...

A simplified simulation method for the calculation of conducted electromagnetic interference (EMI) caused by switched power converters (SPCs) is presented. The method presented here is based on a “sourcepropagation-pathderived disturbance” simulation process and is specially designed to simplify the mentioned computation problems. In the design of the proposed method, quick and robust simulatio...

A new current-source control technique is proposed to design a low-power high-speed multiplevalued current-mode (MVCM) integrated circuit in a low supply voltage. The use of a di erential logic circuit (DLC) with a pair of dual-rail inputs makes the input voltage swing small, which results in a high driving capability at a lower supply voltage, while having large static power dissipation. In th...

A novel low-voltage two-stage operational amplifier employing resistive biasing is presented. This amplifier implements neutralization and correction common mode stability in second stage while employs capacitive dc level shifter and coupling between two stages. The structure reduces the power consumption and increases output voltage swing. The compensation is performed by simple miller method....

To develop a well designed practical spring-roll dielectric elastomer actuator system, we have to optimize its design parameters. In our pervious work, we have achieved the design parameters without taking the applied voltage required to activate the actuator into consideration because the applied voltage might change the optimal design parameters. In the paper, optimal design parameters have b...

This paper surveys the results of an extended research activity concerning the effects of radio frequency interference (RFI) on integrated circuits (IC's). Initially, the possible injection methods for conducted and radiated interference are presented, discussing their applicability and limitations. Then, the basic results of the susceptibility analysis of operational amplifiers and smart power...

— The theory of synergetic control is introduced in a power electronics context in a previous paper. In this paper we review the theory, then we focus on a comparison with the sliding mode approach. Common elements and main differences are underlined and illustrated through a comparative simulation example. The main advantages of synergetic control are that it is well-suited for digital impleme...

Single-switch inverters such as the conventional class E inverter are often highly load sensitive, and maintain zero-voltage switching over only a narrow range of load resistances. This paper introduces a design methodology that enables rapid synthesis of class E and related single-switch inverters that maintain ZVS operation over a wide range of resistive loads. We treat the design of ClassE i...

This paper proposes a transformer-assisted pulsewidth-modulation zero-voltage-switching neutral-pointclamped (NPC) inverter. With the assistance of a transformer-assisted small-rating lossless auxiliary circuit, the main switches work with zero-voltage switching without suffering from any voltage/current spikes, under simple explicit control. The technique allows for higher operating frequency ...
