Gate driver coreless transformer for magnetic resonance imaging power electronics

A gate driver circuit includes an isolated gate driver power supply circuit. The isolated gate driver power circuit includes a coreless transformer including a primary winding and a secondary winding. The secondary winding is wound around the annular non-magnet, and the primary winding is a single turn primary winding to reduce capacitive coupling between the primary winding and the secondary winding. The isolated gate driver power circuit also includes a resonant converter coupled to the coreless transformer, wherein the resonant converter is configured to enable the isolated gate driver power circuit to generate an output voltage independent of the load. 一种栅极驱动器电路，该栅极驱动器电路包括隔离栅极驱动器电源电路。该隔离栅极驱动器电源电路包括无芯变压器，该无芯变压器包括初级绕组和次级绕组。次级绕组围绕环形非磁体缠绕，并且初级绕组是单匝初级绕组，以减小初级绕组和次级绕组之间的电容耦合。隔离栅极驱动器电源电路还包括耦合到无芯变压器的共振转换器，其中该共振转换器被配置为使得隔离栅极驱动器电源电路能够生成独立于负载的输出电压。
