“…A buck-type DC-DC converter circuit is employed as the control. When the amount of solar radiation varies, buck converters are used to stabilize solar panel output so that the proper voltage level can be attained to charge the accumulator [7], [8]. It requires a tool to improve solar cell efficiency as a result of these issues.…”

Although fossil fuels are still readily available, their use is becoming less and less common. Solar energy produced by panels on the roof can be used as a source of power. Semiconductor-based solar panel technology can absorb photons from sunshine and transform them into ecologically beneficial electrical energy. Of course, a control device that regulates the electrical energy charging system is required when using solar cells as a power source to charge a battery. This device is typically referred to as a charge controller. The DC-DC converter of the buck type with a Ziegler Nichols-based Proportional Integral Differential (PID) control approach utilizing Arduino Uno is the control system utilized in this solar cell battery charging. The buck converter reduces and stabilizes the solar panel's output voltage following the requirements for charging the accumulator. For charging batteries, a set point voltage of 13.8 V is employed. By testing the converter with both static and dynamic loads, the research that has been done can produce results. The 35 Watt lamp static load test results with a fixed voltage source show that the set point voltage is 13 V and that it takes 28 s to attain a steady condition. When applied to dynamic loading using a battery charge of 12 V/7.5 Ah with a 20 WP solar panel source during hot, partly cloudy weather, the charging efficiency is 68 percent. A steady state of about 28 s may be claimed to be a satisfactory control system response.

“…These right-half-plane zeros makes the system more sluggish and the conventional current control methods are not appropriate for improving dynamic performance of the converter. In addition, average current mode control method (Carbajal-Gutierrez et al, 2005) may not be suitable for higher order topologies. Generally, the state space averaging method is used for small-signal modelling of DC-DC converters in average current mode control and the higher order dynamics are omitted.…”

The DC-DC converters are well-known due to their nonlinear and time-variant nature. This paper addresses the investigation of a fixed frequency pulse width modulation (PWM) based sliding mode current controller applied to quadratic buck converter (QBC). The QBC is well-suited for very low voltage central processing unit (CPU) voltage regulator applications with high-step-down DC-DC conversion ratios. The sliding mode current control features the reference current profile generation, satisfaction of hitting, existence and stability conditions besides the selection of sliding surface parameters. The simulation of QBC is realised for 19 V~8 V/1V at 50 KHz using PSIM software. The experimental results are presented in order to validate the simulation results. The strength of this control strategy is analysed for both line and load regulations.

An internal model control with conditional integrator is proposed for the robust output regulation of single-switch quadratic buck converters. The output regulation problem of a quadratic buck converter is converted to the stabilization of an augmented system consisting of the buck converter and the internal model. The design procedures include the design of an internal model with conditional integrator and a robust state feedback stabilizer with saturation behavior. The closed-loop stability of the converter will be theoretically analyzed. Finally, the effectiveness of the proposed control scheme for large load and supply variations are also tested. The design of the controller does not require the exact circuit parameters and the stability proof demonstrates the robustness against parameter uncertainties.
