Improved Power MOSFETS Boost Efficiency IN A 3.5kw Single Phase PFC -
This paper charts the technological evolution of APT’s powerMOSFETs from the
earliest PowerMOS IV designs to the latest PowerMOS 7TM products. The
improvement in performance of a 3.5kW boost converter equipped in turn with
different generation products is evaluated, as well....( app note added

Isolated MOSFET driver has wide duty-cycle range - 29-Apr-04 Issue of EDN
The main application for the circuit in Figure 1 is for driving power MOSFETs with
signals ranging in frequency from 1 Hz to 300 kHz and with duty cycles from 0 to 100%.
You achieve this goal by using a coreless pc-board transformer. The switching
frequency in most power-electronics circuits ranges from a few hertz to a few hundred
kilohertz....[Design Idea by Jesus Doval-Gandoy and Moises Pereira Martinez, ETSI

Low-Cost MOSFET Quashes Power Resistor - 06/09/94 EDN-Design Ideas....At
power-on, off-line power supplies use a resistor to provide start-up current for the
PWM IC, current that is necessary to start driving the power switch. After a few
periods, an auxiliary winding delivers a sufficient voltage to power the IC.
Unfortunately, the start-up resistor dissipates heat and....EDN is migrating links.
