With the projected growth of electric vehicles, there is a need for well-planned and equitable investment in the charging infrastructure. Connected vehicle data holds immense promise to understand the usage of electric and hybrid vehicles and thus inform policy. This paper discusses the use of connected vehicle data to inform decision makers on those investments….
Abstract As electric vehicles (EVs) become more prevalent, there is growing concern regarding their impact on transportation and power networks. Using vehicle-to-grid (V2G) technology, EVs can operate as additional energy storage sources that make the power grid more efficient and reliable. With their onboard battery, EVs can relocate energy supply spatially and temporally. In this…
Abstract This paper explores the movement of connected vehicles in Indiana for vehicles classified by the NHTSA Product Information Catalog Vehicle listing as being either electric (EV) or hybrid electric (HV). Analysis of trajectories from July 12-18, 2021 for the state of Indiana observed nearly 33,300 trips and 267,000 vehicle miles travelled (VMT) for the…

RMP President and CEO Gary Hoogeveen and other company leaders took part in the tour and discussed future collaborations with ASPIRE. Student representatives were also present. Rocky Mountain is one of the…
Traditional H-bridge based Wireless Power Transfer (WPT) systems used in electric vehicle (EV) charging possess many challenges in high power applications such as fast charging and dynamic charging. Although multilevel converters are suitable for high power applications, existing multilevel converter based WPT systems have many drawbacks such as the need for independent DC sources and…
This paper presents design of an isolated high-step-down DC-DC converter based on a class-DE power stage, operating at a 10 MHz switching frequency using enhancement mode Gallium Nitride (GaN) transistors. The converter operating principles are discussed, and the power stage design rated for 20 W is presented for a step-down from 200-300 V to 0-28…
Distributed energy generation (DEG) solely based on renewable energy sources (RES) provides a promising solution to today’s climate problems. However, DEG systems negatively impact grid stability. As such, researchers have proposed the utilization of electric vehicles (EVs) in order to improve grid stability through the provision of real and reactive power. Such schemes are known…
Zero voltage switching assistance design for DC-DC series resonant converter with constant input current for wide load range In under-sea dc power distribution systems, constant current feed is preferred over constant voltage feed for robustness against long distance cable impedance. The input voltage of each power converter module in a series connected dc power distribution…
Isolated grid-connected inverters are typically constructed of two stages, namely a voltage-source inverter stage and an isolated bidirectional dc-dc converter stage. Recently, two dual-bridge isolated series resonant dc-dc converters are used to synthesize segments of the line current and reconstruct the complete sinusoidal line currents using a three-phase unfolder. The unfolder technique synthesizes high quality…
Ultrasonic applications require precise knowledge of the dispatched wave in order to process the returning signal. In this work, a cost effective two stage resonant sinusoidal source is presented, capable to adjust on demand both frequency and amplitude of the sinusoidal output. The source tunes automatically to the load parameters using pre-calibration, and is able…
