Constant Frequency ZVS PWM Converter
2021 IEEE Transportation Electrification Conference & Expo (ITEC), 2021 In this paper, a simple yet novel buck or boost adaptive zero-voltage switching (ZVS) converter topology is proposed for soft switching pulse-width modulation (PWM) dc / dc converters. The converter is designed for the high switching frequency that can achieve high efficiency by reducing switching losses for the entire load range at low and high power.

Electronic dynamics and frequency-dependent effects in circularly polarized strong-field physics [PDF]
, 2014 We analyze, quantum mechanically, the dynamics of ionization with a strong, circularly polarized, laser field. We show that the main source for non-adiabatic effects is connected to an effective barrier lowering due to the laser frequency.
