Resonant converter

A resonant converter, comprising:

• a primary circuit, having a first positive line and a first negative line, and comprising primary switches electrically connected between the first positive line and the first negative line of the primary circuit;
• an integrated transformer, electrically connected to the primary circuit;
• a secondary circuit, electrically connected to the integrated transformer, having a second positive line and a second negative line, and comprising secondary switches electrically connected between the second positive line and the second negative line of the secondary circuit;
• and
• a local ground, a first Y capacitor and a second Y capacitor, wherein the first Y capacitor is coupled between the local ground and the first positive line or the first negative line of the primary circuit, the second Y capacitor is coupled between the local ground and the second positive line or the second negative line of the secondary circuit, and the first Y capacitor, the second Y capacitor and the local ground are configured to circulate common mode noise currents between the primary circuit and the secondary circuit.
