“…To find the optimal phase shift ratios, the first thing is to select a proper parameter to indicate the amount of circulating current. There is a wide choice in literature, in the time domain analysis, the total power losses [45], [48], reverse power [46], [55], RMS value of inductor current i L [58], [59] and current stress (I s in Fig. 9) of i L [46], [49], [56], [57] have been used.…”

“…The duty cycle methods that adjust D 1 and D 2 to let the equivalent gain M close to unity, can assist the ZVS-on according to (7). Nevertheless, the TPS methods with minimum circulating current [55]- [58] cannot achieve ZVS-on in the whole operating range as explained in end of Section II. Actually, certain circulating current is required to charge and discharge the capacitance of power devices and the TPS methods derived using FCA [39], [52], [53] have a wider ZVS-on operating range.…”

Dual active bridge (DAB) dc-dc converters have several attractive features including autoadjust bidirectional power flow, wide voltage gain range, and zero voltage switching (ZVS)-on capability. Various applications based on DAB including solid-state transformer in power grids and traction, energy storage system, and electric vehicle on-board chargers have been proposed by academics. Nevertheless, industrial applications based on DABs are still seldom mainly due to the circulating current and loss of ZVS problems under certain load and voltage gain conditions. There is an intensive research effort underway to solve these problems recently. This paper presents the state-of-the-art view in the cause of circulating current and loss of ZVS and surveys the solutions to these problems. INDEX TERMS Circulating current, dc-dc converter, dual active bridge, reactive power, ZVS-on.

Unified harmonic based power calculation for the bidirectional dual active bridge

et al. 2018

View full text Add to dashboard Cite

Dual active bridge is a promising bidirectional topology characterised by its versatility and operation. Power calculation is based on the average current flowing through the load. Therefore, power calculation becomes rigorous task as separate computation is needed for each mode. To mitigate the complexity of the power computation, a novel unified harmonic based power calculation has been proposed.

This study analyses a novel technique for obtaining a voltage conversion ratio greater than one in a bidirectional seriesresonant DC/DC converter (SRC). The converter works in a discontinuous mode: it transfers energy in packets, but it also accumulates some packets in order to raise the output voltage. This study presents a comprehensive theoretical analysis for the two modes: the step-down mode (common mode) and the novel step-up mode. The converter transfers energy during fixed time intervals (called states), and it is also able to accumulate energy in a novel state called the accumulation state. With this, the circuit can achieve a voltage conversion ratio of up to two. In addition, a design methodology is presented, and it is validated in the design of a high-current bidirectional DC/DC converter for battery applications. The results of the voltage conversion ratio and efficiency measurement are presented along with a comparison with an resonant LLC converter. The converter reaches an efficiency rate of 91% and the voltage conversion ratio varies from 0.8 to 1.22 at maximum power. Using this novel technique, the SRC can now be used in a bidirectional DC/DC converter applied to energy storage devices, such as batteries or supercapacitors.
