A novel bidirectional DC-DC topology for electric vehicles using PSIM

A High-Gain Multiphase Interleaved Differential Capacitor Clamped Boost Converter

“…The terminal load (i.e., output voltage), V 0 , is given by: proposed and discussed in this paper. The phase interleaving feature enables the usage of the converter for high-power applications, which is why this topology is chosen over others with high-gain properties [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. This converter has applications in areas such as renewable energy conversion, microgrids, and electric vehicles [26][27][28].…”

“…The voltage reference employed for both capacitors is the same in order to ensure identical mean voltage conditions in the capacitors (24), as well as similar average current conditions in the phases of the same module (25). Figure 8 illustrates that the current reference for the three phases of the same module is the same.…”

“…However, this approach suffers from huge voltage spikes caused by the transformer's leakage inductance, resulting in power loss in the switch. Thus, non-isolated BDCs [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] are chosen over isolated BDCs due to their various advantages, such as their higher efficiency, greater reliability, and lower component count, which leads to a smaller size and lower overall cost [5,6]. In general, a high duty cycle is used to achieve high gain in transformerless converters.…”

“…However, there are several issues with CI-BDC converters, such as energy leakage from the connected inductor, which causes voltage stress during the turn-off process, in addition to the complexity of the circuit design. On the other hand, the cascading of converters increases the component count, enlarges the size, and decreases the efficiency [23][24][25][26]. Hence, to address the abovementioned issues, the interleaving concept is adopted in this manuscript to derive new types of converters, as this approach can also alleviate the drawbacks of both isolated and non-isolated BDCs, such as the voltage stress, high voltage diversity factor with large duty cycles, and high costs.…”

“…With the aim of achieving higher voltage gain than with a conventional boost converter, the alternative topology (interleaved double dual-boost (IDDB) converter [16,17]) is With the aim of achieving higher voltage gain than with a conventional boost converter, the alternative topology (interleaved double dual-boost (IDDB) converter [16,17]) is proposed and discussed in this paper.
