Explain the operation of a buck-boost converter and its primary application.

What are the fundamental limitations of traditional "hard-switched" PWM converters, and how do resonant or "soft-switching" techniques like Zero Voltage Switching (ZVS) and Zero Current Switching (ZCS) overcome these limitations to achieve higher efficiency and power density?
Answer : This question addresses the critical challenge of **switching loss**, the primary barrier to increasing the operating frequency, and therefore the power density, of modern power converters. ** ... state-of-the-art applications like server power supplies, EV chargers, and renewable energy inverters....
