“…The voltage and current-fed IBDCs are full bridge converters [69]- [71], it [71] has two cells with four bridges and two HF isolation transformers, one cell can transfer 50% of power in the case of failure of another cell. Voltage-fed current double converters [72], [73] current source push-pull converters [58], IBDC converters using an asymmetrical PWM modulation scheme can be seen with more than one switch [74]- [76]. These converters can be applied for high-power applications.…”

“…Other advantages of current source converters are high step-up ratio and multiport interface capability, and wide input voltage range operations. One of the disadvantages of CIBDC converter is the unequal distribution of the current stress within the common legs due to the unsymmetrical structure of the converter [73], [80].…”

Among the DC-DC converters, an isolated bidirectional dual active bridge converter is a core circuit for high-frequency power converters in distributed energy system applications. These high-frequency power conversion systems attract academia and industry due to various advantages, such as high-power density, less weight, reduced noise, high efficiency, low cost and high reliability. First, the importance of power electronic converters in modern-day life is introduced. Second, a topological overview of voltage-fed and current-fed isolated bidirectional dual active bridge converters is presented with their importance in integrating hybrid power sources. Third, switching modes of isolated bidirectional DC-DC converters are also presented with a degree of freedom of control. Forth, performance evaluation of voltage-fed and current-fed isolated bidirectional converters has been presented with an example. Their suitability in integrating fuel cells and photovoltaics with energy storage systems in low to medium-power applications is presented.
