The role of thin Film Capacitors in the Field

 Application in power electronic circuit. The thin film capacitor is used in this area, which mainly acts as a buffer of electric current, clamping, resonant bypass and restraining the electromagnetic interference of power supply and so on.

    When the thin film capacitor is used as a bypass, it mainly reduces the impedance of DC bus and absorbs the ripple current from the load, which effectively inhibits the fluctuation of DC bus voltage due to the sudden change of load.

    When the device is used in the resonant converter, it can perform the function of resonant with the inductor.
