Ultrahigh frequency MHz high power conversion device

The invention discloses an ultrahigh frequency MHz high power conversion device, which is characterized in that the device carries out combination on a power electronic topological structure, and can acquires new energy through combining N pieces of energy whose frequency is f, wherein the frequency of the new energy is Nf, and the power of the new energy is N times greater. The combination can be a combination of a single tube forward topology, a single tube flyback topology and a full-bridge topology or a half-bridge topology. The energy can adopt single-phase output or multi-phase output. The energy can be current signals or voltage signals. The ultrahigh frequency MHz high power conversion device has the beneficial effects of simple structure, high reliability, ultrahigh output frequency, and ability of being applied to ultrahigh frequency high-power power electronic devices.
