Abstract
Power switching systems often benefit from controlling the instant at which the power devices change state so as to minimize dissipation in these devices. Such systems often require fairly tight tolerances on reactive components and a relatively narrow frequency operating range to be certain these switching times occur as intended. This invention defines a system that can adapt the required switching instant over very wide changes in the reactive components.
