Arrow Electronics launches integrated bi-directional power converter solution for advancing vehicle-to-grid technology


Solution integrates Silicon Carbide MOSFET technology to yield greater power conversion and smaller form factor benefits

 

HONG
KONG, CHINA – Media OutReach – 14 May 2020 – Global
technology-solutions provider Arrow Electronics today launched an integrated
bi-directional power converter solution for equipping electric vehicles (EVs) with
a robust mobile energy charger, capable of both storing electricity and
contributing excessive energy to power homes and network grids if needed.  Advancing such vehicle-to-home (V2H) and
vehicle-to-grid (V2G) capabilities helps smooth momentary spikes in electricity
demand, capitalize on untapped energy sources during battery idle period, and
thus promote a more sustainable and energy-efficient development of smart
cities.

 

Electrifying transportation has been regarded as one of the key drivers
in addressing global climate challenges. 
According to the International Energy Agency, by 2030 there will be 125
million EVs touring around the world’s highways and byways.[1] As
EV adoption is on the rise, there is growing concern about the operation of
current energy grid infrastructures.

 

V2G and V2H will enable both energy storage and contribution of
excessive energy back to the network grid and community. With the bidirectional
converter, EVs can be used to supply electricity to a house or a building which
then help reduce pressure on the national supply grid.

 

The bidirectional power
converter solution consists of three key elements for implementing a scalable,
cost-effective and energy-efficient converter: a high-efficiency bridgeless
power factor correction (PFC); a V2G bi-directional charger; and a communication
module protocol (EVCC) in
compliance with ISO15118 standard.  Compared to traditional silicon materials,
the PFC and DC-DC power supply with silicon-carbide MOSFET technology result in
less power loss (up to 96% efficiency), smaller form factor (up to 50% reduction),
and lighter weight.  In addition, the
number of individual components utilized in this solution has been reduced by
20%, thus offering a more cost-effective system design.  The solution can support AC-to-DC
bidirectional power conversion with AC voltage range from 200Vac to 265Vac and
the DC voltage range from 250Vdc to 450Vdc. 
The maximum output power is 6.6kW.
