“…For the boost block, the amount of the inductor and capacitor have been selected based on Equations (44) and (45) in order to guarantee the working condition in the CCM state. Also, in order to present the actual conditions in the inductor, a resistance with a serial connection has been added to the inductor.…”

“…[47][48][49] The classic PI and PID controllers make the system have the overshoots and undershoots for a long time and sometimes the damping time of the system is not at an acceptable level. [42][43][44][45][46][47][48][49][50] Furthermore, the amplitude of the output signals at the sudden changes in input voltage or output loads moments with these overshoots and undershoots values are not desired. These controllers need a detailed and accurate mathematical model of the converter and do not advise for the non-linear topologies with uncertain data.…”

Summary PV‐based and wired type of the electrical bicycles (e‐bike) battery charging stations widely is spreading because of the resonant network limitations and low efficiency of the wireless mode for these stations. The generated voltage of many of the PV panels such as JIYANGYIN HR‐200 W‐24 V at the maximum power point is around 36VDC. So, a step‐down converter with a PID controller for Maximum Power Point Tracking (MPPT) of the PV panels is considered between PV panels and boost converter in order to decrease this voltage and enhance the current values for the load side. A sliding mode controller (SMC) equipped with a non‐isolated DC‐DC boost converter with reduced voltage stresses on the power switch is presented. The step‐up converter increases the voltage to the utility level of the e‐bike with around 360 Wh amount of energy. The main concerns about the converters are the efficiency, voltage, and current stresses, number of active or passive components in the converter topology and simplicity. In comparison with a conventional step‐up converter, the selected converter has a lower dynamic loss in the input inductor that can give a proper efficiency by considering its higher voltage gain. The average state‐space model for the SMC is used and the main advantage of the controller is its independency to the inductor current or the amount of the load. The proposed SMC is compared with PID and Fuzzy Logic Controller (FLC) methods and based on the results, the robustness, overshoot, and damping factor of the controller are at an acceptable and better level. All mathematical, simulation and comparison results are presented. A 720 Wh circuit has been implemented for charging all types of the Li‐Ion or Li‐Polymer batteries with 36VDC and 10 Ah specifications.

The basic idea of the circuit fault diagnosis method based on fault logic is to establish a computer expert database system first, connect the computer to the GPIB interface card, and then connect each intelligent instrument through the GPIB standard bus. Through the connection of the tested object adapter and the tested object, a circuit fault expert diagnosis and test platform are formed. Based on the traditional fault simulation model, this paper improves the fault logic circuit of switching power supply, designs the system model of fault simulation, deals with the logic structure and circuit hierarchy respectively, and produces the final output through the logic gate circuit by comparing the results of the fault logic circuit and the fault-free logic circuit. The designed switching power supply fault logic circuit works in the switching state, which has the characteristics of low loss and high energy conversion efficiency. Through the simulation analysis, the output is connected to the comparator, which plays the role of the whole wave. The simulation results are in line with the parameter indicators. The functional test results of the chip show that the function of the module is basically normal, which has practical application value and good portability and can be used as a reference for similar electrical designs.
