Power electronics began in 1902 with the invention of the rectifier. Above all, power electronics enables the conversion of electrical energy in relation to the voltage form, the level of voltage and current and the frequency . Advances in microelectronics have also led to further improved control and regulation options in the field of power electronic components and have thus made power electronics more important. At Solicomp you will find a large selection of discontinued and current power semiconductors from many well-known manufacturers.
