“…Nevertheless, due to the need for separate connections between every two ports, the number of converters may be large while the efficiency is low, and the reliability of the power supply system is hard to guarantee. Since Caricchi proposed the concept The main control circuit frequently employs a single-chip microcomputer with Pulse Width Modulation (PWM) [15], which generates a PWM waveform through a specific algorithm [16], and then controls the on-off of the MOSFET via the drive circuit, which can change the output voltage [17][18][19]. Finally, it transfers energy from the analog photovoltaic cell to the load and the analog battery pack.…”

In this paper, the photovoltaic cell is combined with the analog battery pack and the load through a three-port DC-DC Buck circuit, which gives power to the analog battery pack and load. From the perspective of simulation, the photovoltaic cell is lowered to reach respective specific values through the two Buck circuits at the output end of it and to give power to the load and the simulated battery pack. The influence of Pulse Width Modulation (PWM) duty ratio output on voltage and the influence of PWM frequency on load voltage and current limiting resistance of the power supply system is studied from the angle of power conversion. The results show that when the PWM duty ratio is changed, the actual output voltage does not reach the theoretical value, and is somewhat less than the theoretical value. When the frequency is less than 100 KHz and the inductance value is less than or equal to 100 uH, under the same other conditions, the load voltage decreases first and then increases with the increase of frequency. The larger the inductance value is, the faster the voltage drops, and the smaller the inductance value is, the faster the voltage increases. When the inductance reaches 250 uH, the inductance value continues to increase, which has little influence on the load voltage, and the load voltage generated by different inductance values only has a small error. If the output frequency of PMW is too high or too low, the output voltage will be reduced. The maximum voltage value is between 90 and 100 KHz. When the current limiting resistance is 18.5 Ω, it is close to and does not exceed the maximum charging voltage of the analog battery string.

“…These converters were first time distinguished in 1999; however, their background is longer. Generally, the coupling method in multi‐input converters is categorized into three types [1]: Magnetic coupling [2–5], electrical coupling [6–16], and switch‐mode coupling [17–26], as shown in Figure 1.…”

Here, a new two‐input step‐up DC–DC converter for electric vehicles (EVs) and renewable energy systems (RESs) is proposed. It requires few components and provides high step‐up voltage gain and high efficiency. The topology includes two input channels connected to two energy sources based on the “switch‐mode coupling” method. Sources supply the load via the proposed converter. Each source can charge another if it is rechargeable. The regenerative output side energy is also transmitted to the rechargeable source thanks to the bidirectional power transferring capability. Current sensitive resources can be employed as the converter operates with the continuous input current. The topology comprises only one main power switch located on the low‐voltage side; therefore, it is exposed to low voltage stress and can be readily picked up from low voltage rating semiconductors with small on‐resistance. Thanks to this feature, the conduction loss decreases considerably. The input and output terminals have a common ground. This paper demonstrates the theory and operating principle of the proposed topology. Experimental results are also presented and examined to verify the converter. For this purpose, a 48/400 V/1 kW prototype has been designed and built. Results confirm the converter and its operation.

There are many important trade-offs and constraints on cost, volume, weight, conduction losses, switching losses, microcontrollers, isolation, voltage and current levels, voltage and current ripples, battery specifications, charging–discharging algorithms, control system, switch gate drivers, and efficiency of battery chargers in electric vehicles. In this paper, a well-known power electronic topology commonly used in recent relevant studies is considered, and some important technical considerations with regard to the mentioned trade-offs and constraints are discussed in detail for the first time. The discussion concerns the practical and theoretical experiences in implementation of battery chargers and charging stations of electric vehicles exclusively, and it can be extended to various other power electronic topologies.
