I have supervised graduate students in electrical engineering, guiding their Master’s thesis research in power electronics, control systems, and energy systems. My supervision emphasizes rigorous theoretical analysis, model-based design, and the development of research suitable for peer-reviewed publication, with several projects contributing to conference and journal outputs. Many of my former students have pursued academic careers and currently serve as lecturers at institutions such as the National Polytechnic Institute of Cambodia (NPIC), the National Technical Training Institute (NTTI), and the Industrial Technical Institute (ITI). These outcomes reflect a sustained focus on research quality and the development of academically oriented engineers.

Our laboratory has actively developed a series of advanced hardware modules to support research and experimentation in power electronics and digital control systems. All hardware platforms were fully designed, implemented, and tested by our lab members, demonstrating strong capabilities in both circuit design and embedded system integration.

ADC Modules

The Analog-to-Digital Converter (ADC) modules were developed to provide accurate and high-speed signal acquisition for real-time control applications. These modules are designed with proper signal conditioning, noise filtering, and isolation considerations to ensure reliable measurement of voltage and current signals in power electronic systems.

Gate Driver Modules

The gate driver modules were designed to interface between control boards and power semiconductor devices such as IGBTs and MOSFETs. Emphasis was placed on fast switching performance, electrical isolation, and protection features to ensure safe and efficient operation in high-power applications.

Control Board Featuring TMS320F28335

This control platform is built around the Texas Instruments TMS320F28335 digital signal processor (DSP), widely used in real-time control applications. The board supports multiple peripherals including PWM generation, ADC interfacing, communication protocols, and protection circuits, making it suitable for applications such as grid-connected converters and motor drives.

Control Board Featuring TMS320F28377D

An advanced control board based on the dual-core TMS320F28377D DSP was also developed to handle more complex and computationally intensive applications. This platform enables high-performance control with enhanced processing capability, expanded peripherals, and improved flexibility for multi-loop and multi-variable control systems.

All of these hardware modules reflect the hands-on design experience and technical expertise of our lab members, supporting both academic research and practical implementation in modern power electronics systems.

The developed DC–AC power converter prototype is a versatile experimental platform designed by our research team for studies in power electronics and control systems. It integrates key components including the DC-link, control board, gate drivers, IGBT switching stage, sensing circuits, and output filters.

The system enables flexible implementation and testing of various control algorithms, making it suitable for both research and educational purposes. With accurate voltage and current sensing, along with properly designed filters, the prototype ensures reliable operation and high-quality output performance.

This platform has been widely used in our laboratory for experimental validation, contributing to multiple research publications. All hardware components were fully designed and developed by our lab members, demonstrating strong expertise in power electronics system development.
