6 FAQs about [800V high voltage to low voltage inverter]
What is a 800 volt inverter?
Inverters specifically designed for a voltage of 800 V also contribute to more comfortable acceleration behavior of the vehicle in the drive system, in addition to shorter charging times. Compared to the previous generation, the 800-V inverter presented in the following delivers twice the voltage and offers 2.7 times the power density.
Why do electric vehicle drives have 800-v technology?
Electric vehicle drives with 800-V technology allow higher charging power and thus shorter charging times compared to systems with lower voltage levels.
What is a high-voltage traction inverter?
The market for automotive powertrain electrification products like the high-voltage (HV) traction inverter grows as consumers and regulating agencies demand fewer emissions. In response, manufacturers of hybrid and electric vehicles (xEV) have doubled the HV battery level.
Who invented the 800v inverter?
The 800-V inverters for the innovative vehicle of the German manufacturer - a smaller 300-A inverter for the front-wheel drive and a 600-A inverter for the rear-wheel drive - were developed by Japanese automotive supplier Hitachi Astemo, Figure 1.
Does a traction inverter need a backup power supply?
As automotive applications continue to trend in the direction of increased safety, it has become more common to include a high-voltage to low-voltage backup supply in the traction inverter system. The backup power supply powers the low-voltage components if the 12-V battery fails or the HV battery gets disconnected.
How many volts does a power converter need?
These modules can be unidirectional or bidirectional, allowing power flow in either direction. Power levels from 1 kW to 3 kW are typical, with systems requiring components rated at 40 volts on the 12-volt power net and 650 volts to 1200 volts for the high voltage power net of the converter.
