New study suggests electric bicycles are much better than electric cars for cities

Two wheels are better than four. Sure, I’ve been saying it for years, but now a new study is actually backing me up. It turns out that even though electric cars are moving us in the right direction, electric bicycles are actually much better transportation solutions for urban areas. Here’s why…

Transphorm introduces second 900 V GaN FET for three-phase applications

Transphorm,
a provider of Gallium Nitride (GaN) semiconductors, has introduced its second 900
V Field-Effect Transistor (FET), the Gen III TP90H050WS. Transphorm’s devices now
enable three-phase industrial systems and higher voltage automotive electronics
to use GaN.

The FET has a typical on-resistance of 50 mOhm with a 1000 V
transient rating, offered in a standard TO-247 package. It can reach power
levels of 8 kW in a typical half bridge while maintaining greater than 99% efficiencies.
Transphorm says the FET’s figures of merit for Ron*Qoss (resonant switching
topologies) and Ron*Qrr (hard switching bridge topologies) are two to five
times less than those of common superjunction technologies in production, indicating
highly reduced switching losses.

The new FET is designed to be deployed in bridgeless
totem-pole power factor correction (PFC), half-bridge configurations used in DC
to DC converters and inverters. Transphorm says the FET’s ability to support
these topologies at a higher voltage expands the company’s reach to include three-phase
industrial applications, including EV chargers at higher battery voltage nodes.

Transporm plans to introduce a JEDEC-qualified version in Q1
2020. Transphorm’s first 900 V device, the TP90H180PS, with a typical
on-resistance of 170 mOhm in a TO-220 package is JEDEC qualified and has been
available through Digi-Key since 2017.

“Transphorm’s latest 900 V GaN product represents a major
milestone for commercial GaN power transistors as it reaches the 1 kilovolt
mark, an industry first. This paves the way for GaN to be a viable choice at
these higher voltage nodes,” said Transphorm COO Primit Parikh. “With partial
funding from ARPA-E for early risk reduction and Power America for initial
product qualification, this effort represents successful public-private
partnership that accelerates GaN’s market adoption.”

VW launches electric car share program WeShare in Berlin

Volkswagen has launched WeShare, its 100% electric car
sharing program, in Berlin. The program will begin with 1,500 e-Golf vehicles. VW
plans to add 500 additional e-up! vehicles at the beginning of 2020 as well as the
ID.3 after releasing it in mid-2020. WeShare is a “free-floating” system
without rental stations and is operated via an app. An expansion of WeShare together
with ŠKODA, is planned for 2020, first in Prague before expanding to Hamburg.

Initially, WeShare’s service area will cover about 150 km2 around the city center. VW will extend the area in line with the expansion of the fleet. At launch, customers will pay a discounted tariff of $0.19 per minute. From September onwards, VW plans to offer three categories of tariffs, at an average price of $0.29 per minute.

WeShare will recharge its fleet on the public charging
network in Berlin, including newly built charging
points at 70 supermarkets around Berlin
.

Currently, service employees will collect and charge vehicles,
but in the future VW says users will receive incentives for recharging vehicles
themselves.

WeShare is part of VW’s larger “Volkswagen We” ecosystem, which
is a pool of smartphone-based programs and services for personal vehicles. VW
has already launched several “We” services including parking service We Park, We
Experience for personalized recommendations for services near the user, and We
Deliver, which allows users to use their car trunk for delivery services.

“With WeShare, we have tailored car sharing to meet the
needs of users: easy to use with 100% electric operation on green power,” said Volkswagen
Board Member Christian Senger. “With such a consistent, broad offering, we
stand out from the competition.”
