| Zusammenfassung: | A gate driver circuit includes an isolated gate driver power supply circuit. The isolated gate driver power supply circuit includes a coreless transformer including a primary winding and a secondary winding. The secondary winding is wound about a toroid-shaped, non-magnetic body and the primary winding is a single turn primary winding to reduce capacitance coupling between the primary winding and the secondary winding. The isolated gate driver power supply circuit also includes a resonance converter coupled to the coreless transformer, wherein the resonance converter is configured to enable the isolated gate driver power supply circuit to generate an output voltage independent of load. |
