Operation principle of the present utility model is to rise with the minimizing of capacitance with the voltage of electric capacity that mechanical force will be filled with the variable capacitor of certain electric weight, and electric field energy also increases, and promotes the mechanical energy that capacitance reduces and just changes into electric energy.

The course of work of the present utility model is as follows: when condenser capacity is maximum C _mThe time, low-tension supply is passed through D ₁To the variable capacitor charging, charging into voltage on the variable capacitor is input supply voltage U ₁, electric weight Q=U ₁C _mMechanical force makes the variable capacitor rotation, and along with the minimizing voltage increases of capacitance, voltage is greater than U on the variable capacitor ₁Back D ₁End.When the variable capacitance capacitor amount reduced near minimum value and continues to reduce, the voltage on the variable capacitor will be greater than output voltage U _L, D ₂Conducting, variable capacitor passes through D ₂To storage capacitor C _LWith load R _LDischarge electric energy, discharge voltage equals U _LWhen the variable capacitor capacity of rotating to is minimum value Cn, the variable capacitor discharge off.Variable capacitor will continue rotation under the pulling of electric field force, capacitance also progressively increases, because variable capacitor has been emitted electric energy near minimum value Cn the time, electric weight drops to thereupon.After capacitance increased near maximum, the voltage on the variable capacitor will be less than input supply voltage U ₁, this moment D ₁Conducting, low-tension supply is passed through D ₁Electric weight to the variable capacitor replenish lost.When capacitance arrives maximum C _mThe time, electric weight also is sufficient to the Q value.The volume change ratio of variable capacitor is big, and output voltage is just high.The power output of generator and the rotating speed of variable capacitor, the lobe number on the moving stator of capacitor is directly proportional.
