In many low-power applications such as USB adaptors, cell phone chargers, and system bias supplies, the low-cost quasi-resonant/discontinuous-mode flyback converter ...

Targeting the area of high-voltage, high-switching-frequency applications, this family of ESTB (emitter-switched bipolar transistors) suits industrial three-phase auxiliary power supplies and SEPIC ...

The converter described below, based on a silicon bipolarjunction transistor (BJT), can operate at as low as 250 mV, which is probably a record for a converter not based on a JFET or germanium ...

The refurbished electronics market has exploded in 2026, driven by rising new device costs and a growing appetite for sustainability, yet the risk of hidden component failures remains a major concern ...
