Zero Overvoltage Switching (ZOS) can be used for clean switching transitions without overvoltage oscillations, unlimited switching speed, and eliminating switching losses. This paper details the methodology to implement the ZOS phenomenon in high-density and high-performance power electronics. Various factors significantly influence the operating points where ZOS is applicable. These must be considered for developing ZOS-tailored power electronics. A new approach is presented, where external circuitry can adjust the ZOS operating points to the desired power levels. The influential factors are calculated, simulated, and verified by measurements on a prototype. Also, two operating modes are proposed depending on the chosen ZOS-specific design.
