“…For non-isolated topologies, such as Cuk and Sepic/zeta converters, their efficiencies are low [17], [18] as they use cascaded configurations of two power stages. Conventional buck-boost converters are good candidates for low-voltage applications due to their high efficiency and low cost.…”

Abstract-A switched-capacitor bidirectional DC-DC converter with a high step-up/step-down voltage gain is proposed for electric vehicles (EVs) with a hybrid energy source system (HESS). The converter presented has the advantages of being a simple circuit, a reduced number of components, a wide voltage-gain range, a low voltage stress, and a common ground. In addition, the synchronous rectifiers allow zero voltage switching (ZVS) turn-on and turn-off without requiring any extra hardware, and the efficiency of the converter is improved. A 300W prototype has been developed which validates the wide voltage-gain range of this converter using a variable low-voltage side (40V-100V) and to give a constant high-voltage side (300V). The maximum efficiency of the converter is 94.45% in step-down mode and 94.39% in step-up mode. The experimental results also validate the feasibility and the effectiveness of the proposed topology.

“…However, it should be noted here that the two half bridges could have a synchronized duty cycle control rather than 50%. When the duty cycle is 50%, we obtain the easiest and most traditional case of 2 , V 1 V 2 and V 3 V 4 . This paper focuses on the 50% duty cycle case The use of the dual half-bridge topology instead of a dual full-bridge configuration can be justified as follows.…”

ZVS-PWM isolated boost DC-DC converter. It takes the supply from fuel cell battery at the input side compared to the previous full bridge converter, This half bridge converter to produce the same efficiency. The advantages of the paper is to reduce the number of devices and the mean time to reduce the losses, correspondingly to reduce the space and design cost. The system is simple and easy to operate the entire circle without more additional devices. It is used for medium and high power application. Zero voltage switching is applied in all the inverters. It is achieved the power flow in either direction. The circuit is compact packaging and reduce the losses. The simulation results are of closely agree with the theoretical approach a high efficiency achieved by using a minimal number of electronic devices working in the soft switching mode. It is operated at the frequency of 55 khz.Terms DC-DC converter, soft switching, bi-directional power flow, conduction, losses, zero current switching and zero voltage switching.

“…Conventionally, the dual active bridge converter [7] was used for this application, but this converter cannot achieve zero voltage switching [8] in varies range of load variations when input and output voltage rises. Hence to eliminate this problem in control system the phase shift [9] [10] was introduced with the pulse width modulation.…”

The interests on energy storage schemes, bidirectional dc-dc converter and uninterruptible power supplies have been increasing nowadays as there wide researches are undertaken in the area of electric vehicles. A modified bi directional class-E resonant dc-dc converter is introduced here in this proposed topology for the application in electric vehicles. The advantages of soft switching techniques have been utilized for making analysis simple. The main advantage here in this system is that it can operate in a wide range of frequencies with minimal switching loss in transistors. This paper elaborates a detailed analysis on converter design and the same has been simulated and verified in Matlab/Simulink.
