Covers resonant coverters and inverters, and soft switching; sinusoidal approximations in analysis of series, parallel, Lcc, and other resonant dc-dc and dc-ac converters; state-plane analysis of resonant circuits; switching transitions in hand-switched and soft-switched Pwm converters; zero-voltage switching techniques, including resonant, quasi resonant, aero voltage transition, and auxiliary switch circuits. Prereq., ECEN 5797 or instructor consent required.
