Power semiconductors are vital for increasing energy efficiency throughout the electricity supply chain from generation to distribution and finally consumption. Considering constantly rising energy requirements, Infineon’s solutions make a key contribution to securing an efficient energy supply for the world”, said Arunjai Mittal, Division President of the Industrial & Multimarket Division at Infineon Technologies. Power semiconductors enhance the energy efficiency of power supply in electronic devices. In the field of renewables they are instrumental in feeding as much as possible electric power harnessed from wind or solar radiation into the grid, and for minimizing energy loss in transmission from the place where it is generated to the place where it is consumed.
