“…In this scheme, an auxiliary energy storage device such as a super capacitor (S.C.) is regarded as a key device for assisting the operation of the main battery against the repetitive charging/discharging operation and abrupt energy demands from the loads. The bidirectional DC-DC converters developed for S.C. interfacing circuits up to the present time have been mainly nonisolated bidirectional DC-DC converters (current reversible DC choppers) [6], [7]. The non-isolated type circuit topology generally has some advantages such as a simple and light circuit configuration due to the transformer-free circuit topology.…”

“…This leads to deterioration in the energy utilization of the S.C. cells. Several bidirectional DC-DC converter topologies for low voltage/large current power conversion have been presented so far for power supplies in industry, communication and information facilities etc [2]- [4], [7], [9]. However, there are few proposals that are specified for a S.C. interface power converter under the low voltage condition.…”

This paper presents a bidirectional DC-DC converter suitable for low-voltage super capacitor-based electric energy storage systems. The DC-DC converter presented here consists of a full-bridge circuit and a current-fed push-pull circuit with a high frequency (HF) transformer-link. In order to reduce the device-conduction losses due to the large current of the super capacitor as well as unnecessary ringing, synchronous rectification is employed in the super capacitor-charging mode. A wide range of voltage regulation between the battery and the super capacitor can be realized by employing a Phase-Shifting (PS) Pulse Width Modulation (PWM) scheme in the full-bridge circuit for the super capacitor charging mode as well as the overlapping PWM scheme of the gate signals to the active power devices in the push-pull circuit for the super capacitor discharging mode. Essential performance of the bidirectional DC-DC converter is demonstrated with simulation and experiment results, and the practical effectiveness of the DC-DC converter is discussed.

“…The soft-switching techniques for PWM full bridge converter can be classified into two kinds: one is zero-voltage-switching (ZVS) and the other is zero-currentswitching (ZCS). For dc-dc power conversion applications, the conventional phase-shift full-bridge dc/dc converter has drawn more attention in recent decades due to its advantages: high conversion efficiency, high power density, and low electro magnetic interference [3][4][5][6][7][8]. In order to obtain high conversion efficiency for dc-dc power conversion applications, a soft-switched dc/dc converter with a LCC primary-side energy storage elements based on [9][10][11][12] is studied and implemented in this paper.…”

This paper presents an improved self sustained oscillating controller circuit using LCC components for improving the overall efficiency of the system. It has a micro controller based active controller, which controls the performance from no-load up to full-load. The steady state characteristics are developed and a design example is given in detail. The proposed controller allows zero current switching at any loading condition which results in a reasonable reduction of power loss during switching with a promising efficiency. Analytical and experimental results verify the achievement the design specifications.

“…In EV propulsion applications, two-quadrant (2Q) dc choppers are desirable because they convert battery dc voltage to variable dc voltage during the motoring mode and revert the power flow during regenerative braking. Bidirectional dc-dc converters are also developed for energy management purposes of hybrid electric and fuel cell vehicles [Chan, 2007;Zhang et al, 2007]. Furthermore, four-quadrant (4Q) dc choppers are employed for reversible and regenerative speed control of dc motors.…”
