The demand for smaller, lighter, and more efficient AC/DC USB power delivery (PD) chargers is always a challenge for power-supply design engineers. Below 100 W, the quasi-resonant flyback is still the ...

Abstract: Single-phase AC-DC power converters face the challenge of twice-grid frequency power ripple (TGFPR) caused by power imbalance, requiring the use of large DC-side capacitors. Active power ...

The critical role of snubber circuits in minimizing ringing and overshoot. How snubber circuitry is evolving to adapt to trends in power electronics, like the rising interest in wide-bandgap ...

AC/DC have just announced a long-awaited North American tour. It's their first since touring the continent in 2016 with Axl Rose fronting the band in place of Brian Johnson, who was sidelined with ...

The isolated AC-to-DC flyback converter is the most commonly used power supply type for home and industrial devices. The isolated AC-to-DC flyback converter is the most commonly used power supply type ...

California-based startup Enteligent is taking pre-orders for what it calls the world’s first solar DC-to-DC electric vehicle chargers. The unit can take power from a photovoltaic array and send it ...

Part II of Art. 690 provides the circuit requirements for PV systems. The first requirement it covers is the maximum PV system direct-current (DC) circuit voltage. This value is used when selecting ...
