Synopsis
As power conversion architectures evolve toward greater modularity, distribution, and efficiency, there is a growing demand for innovative design methodologies that can minimize energy loss, reduce system complexity, and improve scalability. In this context, Partial Power Processing (PPP) has emerged as a promising solution. Unlike traditional converters that handle the entire system power, PPP architectures allow power converters to process only a portion of the total power, significantly improving overall efficiency and reducing component stress and cost.
Simultaneously, wide bandgap (WBG) semiconductors, such as silicon carbide (SiC) and gallium nitride (GaN), are not only redefining power device performance but are uniquely matched to the requirements of PPP architectures. Their faster switching reduces the volume of partial-power processing stages by enabling higher operating frequencies, while exceptionally low conduction and switching losses directly translate into greater sub-module efficiency. Moreover, the superior thermal conductivity of WBG materials allows PPP converters to sustain higher power densities with simplified cooling schemes. These characteristics, high-frequency operation, minimized energy loss, and robust thermal behavior, make WBG devices the ideal enabler for compact, high-efficiency PPP systems.
This tutorial will begin with a theoretical overview of PPP, followed by an in-depth discussion of WBG device characteristics relevant to partial power applications. Various PPP topologies will be analyzed, along with practical design considerations including topology selection, control strategies, and magnetic component optimization. Case studies and experimental data will be used to illustrate the benefits and challenges of real-world implementations. The session will conclude with insights into emerging research trends, standardization issues, and commercialization opportunities for WBG-enabled PPP systems.
Objectives and Audience
This tutorial is intended to provide participants with a comprehensive understanding of the integration of wide bandgap (WBG) devices and partial power processing (PPP) architectures in advanced power electronics systems.
Objectives:
•      Introduce the fundamental principles of PPP and its distinction from conventional full-power conversion methods.
•      Demonstrate the performance advantages of WBG devices in PPP applications, including higher efficiency, increased power density, and enhanced thermal performance.
•      Present key converter topologies and control strategies tailored for WBG-based PPP systems.
•      Provide design insights covering trade-offs, component selection, and system integration.
•      Showcase application examples in areas such as electric vehicle charging.
Target Audience:
•      Power electronics professionals and researchers developing high-performance converter topologies.
•      Engineers and designers aiming to improve system-level efficiency through partial power processing techniques.
•      Graduate students and early-career researchers seeking foundational and applied knowledge in high-efficiency power conversion.
A basic background in power electronics is recommended, though the tutorial will begin with a brief review to ensure accessibility for a broad technical audience.
