· What are the differences between on-board chargers and household charging stations used in new energy vehicles?

At present, in addition to using external charging stations for charging, the most common charging methods for new energy vehicles are on-board chargers and household charging stations, both of which belong to slow charging. There is a clear difference between on-board chargers and household charging stations.Car charger refers to a charging device that can be carried in the car and can usually be charged using a regular household socket; The household charging station is fixed inside the residential area and needs to be installed and connected to the power grid before it can be used.The main difference between on-board chargers for new energy vehicles and household charging stations is:1. The usage scenarios are different. Car chargers are suitable for temporarily recharging during travel, while home charging stations are designed for convenient charging at home;2. The charging speed varies. Generally, household charging stations charge faster than on-board chargers;3. The installati...

· Variable Speed Drives Solution IGBT7

We could save up to 20% of energy or 17 million tons of CO2 if only half of all industrial drives had an electric speed control. The 7th generation of TRENCHSTOP™ IGBTs is especial designed for variable speed drives. Based on the micro-pattern trench technology, which offer a high level of controllability. These features bring significant loss reduction in the application, especially for industrial drives, which usually operate at moderate switching frequency.Every switch needs a driver and the right driver makes a difference. To make the most out of the design with TRENCHSTOP™ IGBT7, we recommend using gate driver ICs that meet the IGBT7 as well as the industrial drives’ requirements.IGBT7 in industrial drives requires high output current gate drivers that need to have reinforced isolation (VDE 0884-11 certified). Infineon’s EiceDRIVER™ isolated gate drivers within the X3 Compact, 2L-SRC, and X3 Enhanced families meet these requirements while prov...
