ST AN1514 Application Note
This paper introduces two double output off-line non isolated SMPS based on the VIPerX2A-E family. The first SMPS is a Buck converter with two positive outputs and the second one is a Buck-Boost converter with two negative outputs.
ST AN1439 Application Note
ST AN1326 Application Note
This document introduces resonant and quasi-resonant converters which have been developed and proposed as a solution to the difficulties of square-wave converters. Quasi-resonant converters use a tank circuit to create a zero-voltage or zero-current condition for the power switch to turn on or off. Quasi-resonant converters can be classified as Zero-Voltage Switching turn-on (ZVS) or Zero-Current Switching turn-off (ZCS) converters. In ZVS converters, the power switch is dynamically connected in parallel to the tank circuit, and the superposition of the resonant voltage and the DC input voltage generates the zero-voltage condition for the switch to turn on. Conversely, in ZCS converters, the power switch is connected in series to the tank circuit, and the superposition of the resonant current and the normal current flow generates the zero-current condition for the switch to turn off.
