High-level multistep inverter optimization using a minimum number of power transistors
(2006)
Multilevel inverters with a large number of steps (more than 50 levels) can generate high quality voltage waveforms, good enough to be considered as suitable voltage template generators. Many levels or steps can follow a ...
A Monolithic 0.35-mu m SiGe Class E Power Amplifier Designed at 1.9 GHz
(Ieee, 2013-01-01)
This paper presents the design of a monolithic 1.9 GHz, Class E, power amplifier (PA) for wireless application with the main components on chip. A cascode topology is used to attenuate transistor stress and to increase the ...

Non-linear modeling for low and high power microwave transistors
(IEEE Xplore Digital Library, 2017-01-19)
New generation of communications systems will demand the use of low power devices in mesh configuration. This work presents a new characterization procedure for those devices in order to predict their behaviour before the ...
Emitter drive : a technique to drive a bipolar power transistor switching at 100 kHz
(IEEE, 1990)
Theoretical support and experimental results concerning the application of a emitter driven bipolar power transistor to a 400 V, 10 A power switch are presented. The central idea of the emitter drive is to turn off and on ...
New family of zero-current-switching PWM converter
(1999-12-01)
A new family of dc-to-dc pulse-width-modulated (PWM) converters is presented. These converters feature soft-commutation at zero-current (ZC) in the active switches. The new ZCS-PWM Boost and new ZCS-PWM Zeta converters, ...
