A major cause of losses in a conventional power supply using a 50/60-Hz transformer is the bridge rectifier. This article shows how to build a “greener” rectifier, substantially reducing losses by ...

The losses in a bridge rectifier can easily become significant when low voltages are being rectified. The voltage drop across the bridge is a good 1.5 V, which is a hefty 25% with an input voltage of ...

The switching speed of a power MOSFET charge-controlled device depends on the speed with which an associated gate driver circuit can charge its input capacitance. For the last 20 years, many excellent ...

Linear Technology Corporation is claiming a major breakthrough with the introduction of the LT4320, an ideal diode bridge controller for 9V to 72V systems that replaces each of the four diodes in a ...

After discussing the three transistor high-side buck p-mosfet driver (a recognised circuit and not mine) with some of EW’s sage commenters, I wondered once again if I could design something similar ...

The voltage across the capacitor pretending to be the mosfet gate capacitance is not getting close enough to the oV rail (see black rectangle below left) to turn off the mosfet properly – my ...
