calls for sustainable and eco-friendly solutions to reduce environmental impact. Traditional electrotherapy systems rely heavily on disposable components and non-renewable energy sources, contributing to environmental waste. This paper explores the integration of solar power in electrotherapy devices, focusing on the design of a solar-powered system that steps up DC signals using MOSFET technology and photovoltaic (PV) cells. The developed model successfully steps up the voltage, providing a sustainable, portable, and ecofriendly alternative for electrotherapy treatments. The use of solar energy not only minimizes resource consumption but also enhances device portability, making it suitable for off-grid and remote locations. The paper highlights the potential of renewable energy technologies to reduce the ecological footprint of electrotherapy devices while ensuring effective and safe treatment. By combining electrical engineering with electrotherapy, this research paves the way for future innovations in sustainable healthcare solutions.
Furthermore, this paper also explores the conversion of the stepped-up DC signal into both alternating current (AC) and DC outputs for testing purposes. AC output is typically required for treatments like Transcutaneous Electrical Nerve Stimulation (TENS) or Interferential Current Therapy (IFC), while DC output is more commonly used in treatments such as Neuromuscular Electrical Stimulation (NMES). The ability to produce both AC and DC outputs from the stepped-up DC signal makes this system versatile and adaptable to a wide range of electrotherapy techniques, offering flexibility in treatment approaches for different patient needs[3].

To model and simulate this power conversion process, MATLAB 2021a is used as the simulation tool. MATLAB provides an advanced simulation environment that allows for detailed modeling and testing of power electronics circuits. By utilizing MATLAB, the design of the step-up converter that uses MOSFET technology to increase the lowvoltage DC signal is carefully analyzed. The simulation also facilitates the conversion of the DC voltage into both AC and DC outputs for electrotherapy applications, enabling the evaluation of the system’s performance under various conditions[4-7].
1. INTRODUCTION As the demand for sustainable and portable electrotherapy devices continues to increase, solar-powered solutions offer an excellent opportunity to reduce reliance on nonrenewable energy sources while ensuring effective treatment. The ability to power electrotherapy devices using solar energy not only addresses environmental concerns but also enables treatment in remote or off-grid locations where conventional electrical grids are unavailable[1]. However, to ensure that the energy generated by solar panels is efficiently converted into a usable electrical signal for electrotherapy, power conversion technologies must be employed. Specifically, this paper focuses on the use of Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) technology to step up the low-voltage direct current (DC) signals produced by solar panels to the appropriate voltage levels needed for electrotherapy applications[2].
The simulation process begins with the modeling of the solar panel’s low-voltage DC signal. This signal is then fed into the step-up converter, where the MOSFET-based technology increases the voltage to the desired level. The simulation includes both AC and DC output testing, where parameters such as frequency, waveform, and voltage are adjusted for compatibility with different electrotherapy modalities. Through MATLAB simulations, various conditions—such as changes in solar intensity, variations in load, and voltage regulation—can be tested and optimized for better system efficiency and performance[8-10].
