Development of high-speed and high-voltage pulse generator for NO x decomposition plasma reactor
2017 Edition, December 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper proposes a novel high-speed and high-voltage pulse generator for a NO x decomposition plasma reactor for automotive application, which is composed of a DC/DC step-up converter and a multiple-toroidal-core technique. The DC/DC converter steps up 12-V...

Design of a High-Efficiency Minimum-Torque-Ripple 12-V/1-kW Three-Phase BLDC Motor Drive System for Diesel Engine Emission Reductions
2014 Edition, Volume 63, September 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A 12-V motor drive system using an onboard battery is promising in vehicle applications, e.g., to rotate an air pump to adjust its air delivery to the burner, thereby providing autonomous exhaust temperature control for the conventional diesel engine vehicle. The 12-V/1-kW motor drive...

Joint Energy Management and Interference Coordination with Max-Min Fairness in Ultra-Dense HetNets
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Interference management and energy management are two important issues in ultra-dense heterogeneous cellular networks (HetNets). However, load balancing investigated for system capacity on interference coordination is not efficient for energy saving in HetNets. Meanwhile, the...

A Novel 1.4-4.8 GHz Ultra-Wideband, over 45% High Efficiency Digitally Assisted Frequency-Periodic Load Modulated Amplifier
2019 Edition, June 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We report an ultra-wideband and high efficiency sub-6GHz power amplifier, which is based on periodically varied load modulation with frequency. Key novelties are frequency-periodic load modulation over multiple contiguous frequency bands combined with digitally assisted...

Ultra-Thin GaAs Double-Junction Solar Cell With Carbon-Doped Emitter
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We address the challenge in depositing ultra-thin GaAs cells (<200 nm) using a more scalable process (metal-organic chemical vapor deposition). We present results for a GaAs/GaAs double-junction solar cell with a 110-nm-thick top cell. Current, voltage, fill factor, and...

Machine Learning Inspired Codeword Selection for Dual Connectivity in 5G User-centric Ultra-dense Networks
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In future 5G user-centric ultra-dense networks (UUDN), demands of high data rate and high spectrum efficiency (SE) are effectively met by dual connectivity (DC) technology. However, due to huge increase of base stations (BSs) and mobile users (MUs), it becomes difficult...

48 Volts: Time for a Jolt to Vehicle Performance?
September 3, 2015 - IEEE GlobalSpec

It was an idea that emerged in the 1990s with the increasing electrification of internal combustion engine automobiles. As more electric motors, telematics, entertainment and other electronic systems were designed into cars, engineers found themselves knocking against the limitations...

Ultra-Wideband Dual-Mode Doherty Power Amplifier Using Reciprocal Gate Bias for 5G Applications
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A novel architecture to extend the bandwidth of the Doherty power amplifier (DPA) is presented in this article. It is illustrated that two DPA modes at different frequency bands can be realized by simply swapping the gate biases of the transistors without changing the matching circuits, and hence,...

A Compact Dual-Band Digital Polar Doherty Power Amplifier Using Parallel-Combining Transformer
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a dual-band high-power digital polar Doherty power amplifier (PA). A current-mode parallel-combining transformer (PCT) power combiner is introduced for Doherty operation, which realizes simultaneous dual-band coverage, high output power, and backoff...
