Boost converter

A boost converter, comprising:

• a first inductor, receiving an input voltage;
• a first switch element, wherein a first parasitic capacitor is built in the first switch element, and the first switch element selectively couples the first inductor to a ground voltage according to a first control voltage;
• an output stage circuit, generating an output voltage;
• a second switch element, wherein a second parasitic capacitor is built in the second switch element, and the second switch element selectively couples the first inductor to the output stage circuit according to a second control voltage;
• and
• a tuning circuit, comprising a second inductor, a third inductor, and a discharge path, wherein the first parasitic capacitor resonates with the second inductor and is coupled through the discharge path to the ground voltage, or wherein the second parasitic capacitor resonates with the third inductor and is coupled through the discharge path to the ground voltage.
