What are the application areas of IGBT2024-01-10 11:22:08
The main function of IGBT is to convert high-voltage direct current to alternating current, as well as frequency conversion;
1. New energy vehicles
IGBT is the core technical component of electric vehicles and charging stations, playing a crucial role in electric vehicles. It mainly plays a role in the charging stations, electric control systems, and onboard air conditioning control systems of electric vehicles.
(1) Electric control system
Used for driving automotive motors after high-power DC/AC inverter;
(2) Vehicle air conditioning control system
Applied to low-power DC/AC inverter;
(3) Charging station
Used as a switching element in intelligent charging stations;
2. Smart grid
The generation end, transmission end, substation end, and consumption end of the smart grid all require the use of IGBT.
(1) Power generation end
IGBT is required for rectifiers and inverters in wind and photovoltaic power generation.
(2) Transmission end
FACTS flexible transmission technology in ultra-high voltage direct current transmission requires a large amount of use of IGBT.
(3) Substation end
IGBT is a key component of power electronic transformers.
(4) Electricity consumption end
There is a high demand for IGBT in household white appliances, microwave ovens, LED lighting drivers, and more.
3. Rail transit
As is well known, AC transmission technology is one of the core technologies of modern rail transit. In the AC transmission system, traction converters are key components, and IGBT is one of the most core components of traction converters. It can be said that this device has become the mainstream power electronic device for traction converters and various auxiliary converters in rail transit vehicles.
