Features: This book provides a detailed introduction to the design of modern high-frequency switching power supplies using international new-type MOSFET and IGBT electronic power devices, various new IC control systems, and domestic high-quality magnetic materials. Its operating frequency reaches 100kHz, with power capacity ranging from 15 to 3000W. The main converter structures include flyback, forward, half-bridge, and full-bridge designs, featuring both PWM "hard-switching" power supply circuits and popular phase-shifted control "soft-switching" power supply circuits. It particularly introduces design examples of various 15-50W single-ended flyback switching power supplies and 1000-3000W soft-switching phase-shifted control zero-voltage full-bridge converter regulated power supplies, as well as high-frequency active power factor correction circuits.
The book provides readers with an in-depth understanding of many difficulties, fault phenomena, and solution approaches encountered during the prototype development process through a wealth of accurately recorded experimental data and measured waveforms. It presents the working characteristics and control curves of various power supply control ICs measured in practice. The book also explains the practical design methods and construction techniques for main power transformers, driving transformers, auxiliary power transformers, as well as output filter inductors, resonant inductors, and boost inductors for various high-frequency switching power supplies, facilitating the mastery of practical design and construction skills by engineering professionals.
This book is suitable for reference by engineering professionals in the fields of fundamental power supplies, switching power supplies, industrial power supplies, communication power supplies, high-frequency active power factor correction supplies, UPS uninterrupted power supplies, vehicle or aircraft power supplies, and instrument equipment power supplies. It can also serve as a reference for faculty and students in higher education institutions.
