An expert discussion with notes for the hobbyist on how to design power supplies while avoiding supply chain vulnerabilities In Robust Power Supply Design in a Supply-Chain-Challenged World, engineer and power electronics specialist Ron Lenk delivers a comprehensive guide that delves into the intricacies of designing high-performance power supplies that use exclusively multi-source components. After considering robust passive and active components and how to do successful modeling with LTSpice, Lenk focuses on concrete, detailed examples of the design of robust power supplies. Robust design examples include: A 500mV output LDO;A 5mW Boost converter;A 24W Passive PFC circuit;A 48-to-1V, 100A Bang-Bang Converter with Synchronous Rectification for an automotive AI chip;A 277VAC, 5000W PFC for LED stadium lighting; andAn off-line 22KW, 2MHz four-slice EV charger…plus many other topical examples, all designed with little more than op-amps, comparators and 555 timers. Readers will also find: A thorough introduction to multiple types of converters, including bang-bang, PWM, and PFCDetailed specifications, design principles, and simulation of robust convertersPractical discussions of high-speed and high-precision designs, and of system optimizationTreatment of reliability calculations and special topics such as current limiting and negative voltage generationPerfect for power supply engineers, Robust Power Supply Design in a Supply-Chain-Challenged World will also benefit graduate and senior undergraduate students with an interest in power electronics and power systems. Each chapter has a special section with tips for the Hobbyist interested in designing and building their own power supplies.
