Synthesis of Near-Zero Emissions Power Converters - Part 1 (pdf, 194k) describes the synthesis of power conversion circuits that have the property of non-pulsating input and output terminal currents and cancellation of common mode noise.
Synthesis of Near-Zero Emissions Power Converters - Part 2 (pdf, 156k) describes how to extend the new synthesis methods to achieve converters with zero ripple.
Synthesis of Near-Zero Emissions Power Converters - Part 3 (pdf, 190k) describes how to apply similar synthesis methods to isolated full bridge and half bridge circuits to achieve equivalent converters with terminal ripple currents and common mode noise cancellation.
Synthesis of Near-Zero Emissions Power Converters - Part 4 (pdf, 175k) describes how to apply synthesis methods to isolated single-ended flyback and forward converters and push pull converters to achieve equivalent converters with terminal ripple current and common mode noise cancellation.
High Side Drive (pdf, 361k) describes a high side driver circuit that uses no level shifting circuits, high voltage semiconductors, or magnetics, but has efficiency and speed comparable to a gate drive transformer. This high side driver can be used with N channel mosfets in active reset circuits that have a reference (source) voltage that shifts up and down as the reset (clamp) capacitor voltage varies. This file illustrates the circuit and shows how the circuit is used with some other circuits in practical applications.
High Side Drive 2 (pdf 135k) describes a high side driver circuit that uses no level shifting circuits, high voltage semiconductors, or magnetics, but has efficiency and speed comparable to a gate drive transformer. This high side driver can be used with N channel mosfets in active reset circuits that have a reference (source) voltage that shifts up and down as the reset (clamp) capacitor voltage varies. A complete schematic of the circuit is illustrated.
Optimal Switch Timing (pdf 311k) describes a simple, but effective, optimal switch timing circuit that is useful for zero voltage switches and synchronous rectifiers.
Zero Voltage Switching Active Clamp Flyback Converter (pdf 274k) describes and illustrates in high detail the operation of a high efficiency flyback converter.
