DC Power Supplies | Chapter 7

In this video, we cover Chapter 7 of Power Electronics, which focuses on the design and operation of DC power supplies—complete systems that convert an AC source into a stable, regulated DC output. We begin by examining transformer models and their role in isolation and voltage scaling, then move into detailed operation of common isolated converter topologies, including the flyback, forward, push-pull, half-bridge, and full-bridge converters. Both continuous and discontinuous current modes are discussed, highlighting their effects on performance and efficiency. The video then explores feedback control techniques used to regulate output voltage, including pulse-width modulation (PWM), small-signal modeling, and control loop stability. Key concepts such as compensation networks, pole–zero placement, and error amplifier design are introduced to show how stable regulation is achieved in practical power supplies. Additional topics include power factor correction, AC line filtering, and the integration of all subsystems into a complete DC power supply. PSpice simulations are used throughout the chapter to illustrate dynamic behavior and validate analytical results. By the end of this video, you’ll understand how individual converter stages, control loops, and filtering elements work together to form reliable, efficient DC power supplies used in real-world electronic systems.
