24V Boost Converter (47V) - Quasi-Resonant Conduction Mode, 1st valley

Open online SPICE simulator circuit link: power_optimos_24V_boost_4_QR_1v.tsc


Boost Converter - Quasi-Resonant Conduction Mode, switching in 1st valley

The MOSFET is turned on when V_DS is the lowest after the inductor current has reached zero, resulting in the lowest turn-on losses.

Default settings: 24V DC input - 47V DC output
Input power: 11.46W
Output power: 11.22W
Efficiency: 97.9%
Frequency: 120kHz
