Efficient and compact voltage converters for the e-mobility sector :
The Fraunhofer Institute for Applied Solid State Physics IAF has developed the world's first half-bridge circuit for the important 600 volt class in which all the electronic components are monolithically integrated on one chip. Monolithically integrated half bridges are key building blocks of compact voltage converters and significantly increase the efficiency of power electronics devices. This is thanks to the use of the novel semiconductor material gallium nitride (GaN).

Voltage converters are in high demand. Used in mains adapters and chargers for smartphones, laptops and low-voltage household appliances, they can be found everywhere, and – due to our habit of plugging in more and more electrical devices to the mains power supply – they are becoming increasingly widespread. The energy transition and e-mobility are also increasing the demand for reliable and, above all, efficient and compact voltage converters of all kinds. Half-bridge circuits are the centerpiece of many voltage converters. Fraunhofer IAF has now produced and demonstrated the world's first monolithically integrated GaN half bridge for the important 600 volt class. In power electronics components, this is the standard volt class for grid-connected electrical devices, ranging from tablets and washing machines to e-bikes and electric cars.
