6 Frequently Asked Questions about “Inverter and high power supply”
What is a high voltage inverter?
Typically, they are on the high voltage side (from 30 kV to 150 kV and more), and are made by connecting back-to-back controlled rectifier and inverter employing a DC bus. Dealing with high voltages, classical bridge rectifiers, and two-level inverters are not suitable due to the limited characteristics of electronic switches.
How to choose a power supply architecture for traction inverters?
There are several isolated bias power supply architectures for traction inverters and some commonly-used architectures are shown in this paper. Based on the chosen architecture, the next step is to choose a topology (flyback, push-pull, LLC resonant, integrated DC/DC module, and so forth) and the associated devices.
Do traction inverters 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.
Why is isolated bias power supply important for traction inverters?
Redundancy Only at the High Side in Fully-Distributed Architecture Isolated bias supply is an important part of every traction inverter system. There are several isolated bias power supply architectures for traction inverters and some commonly-used architectures are shown in this paper.
What is a traction inverter?
The automotive industry is transitioning from combustion engines to electric vehicles (EV) and hybrid electric vehicles (HEV). One of the key parts of an EV and HEV system is a Traction Inverter. The traction inverter takes the DC input power from the high-voltage (HV) battery and provides the controlled AC power to the e-motor.
Why should you choose uc28c5x for EV traction inverters?
The new UVLO options and 30-V rating to reliably drive SiC MOSFET with UC28C5x family enable higher thermal de-rating power and optimal switching performance of the backup power supply in the increasingly popular 800-V battery system of EV traction inverters.
