This white paper examines the challenges of efficient high-voltage power conversion and provides examples of component, topology and system-level innovations that help simplify power-supply designs in automotive and industrial applications.

1 Optimizing wide-bandgap FET performance with component innovations
Wide band-gap field-effect transistors (FETs) offer a higher-efficiency alternative to metal-oxide semiconductor field-effect transistors (MOSFETs) but require specialized companion devices such as isolated gate drivers and digital controllers for optimum performance.
2 Maximizing power density with topology innovations
Selecting the right topology can greatly influence the power density and efficiency of a high-voltage power design.
3 Achieving extreme efficiency targets with system-level innovation
System architecture innovations and control system innovations can help designers achieve higher efficiency and power density.
