From the charging unit for smartphones to the power supply of the laptop or washing machine to LED lights or charging stations of electric cars – switching power supplies are omnipresent in electrical devices. They convert the alternating current from the house line into the direct current needed by the device. The problem: power supplies are susceptible to errors, which also reduces the service life of end devices. Researchers of Karlsruhe Institute of Technology (KIT) have now developed a power supply unit with a significantly increased service life.
