Solution of the present utility model is: a kind of brushless claw pole electric generator based on high frequency transformer, comprise housing, pawl pole rotor is provided with in described housing, excitation winding is provided with in the rotor of described pawl pole, in described inner walls, corresponding excitation winding place is installed with stator winding, two ends, rotor left and right, described pawl pole to be arranged on housing by bearing and to pass described housing, its special character is: described pawl pole rotor left end is installed with high frequency transformer rotor magnetic core, high frequency transformer rotor windings is installed with in described high frequency transformer rotor magnetic core, string holes is provided with in the rotor of described pawl pole, rectifier is installed with in string holes, the output of described high frequency transformer rotor windings is connected by the input of rectifier with described excitation winding, the high frequency transformer stator core corresponding with high frequency transformer rotor magnetic core is installed with in described housing exterior walls left side, the high frequency transformer stator winding corresponding with described high frequency transformer rotor windings is installed with in described high frequency transformer stator core, the input of described high frequency transformer stator winding is connected with inverter, and the input of described inverter is connected with storage battery.
The beneficial effects of the utility model are:
1, the high frequency transformer rotor magnetic core that pawl pole rotor left end is set and high frequency transformer rotor windings is adopted to instead of brush with the high frequency transformer stator core and high frequency transformer stator winding being arranged on housing exterior walls left side, without wearing and tearing, extend the useful life of generator, prevent the generation of the phenomenons such as short circuit, part aging, fire.
2, the direct current of storage battery passes to high frequency transformer stator winding through the alternating current that inverter is changed, then by high frequency transformer rotor windings, alternating current is passed to rectifier formation direct current, finally passes to excitation winding, pawl pole rotor forms magnetic flux.Electric current is delivered to high frequency transformer rotor windings from high frequency transformer stator winding, and this process can by the mode booster tension of setting high frequency transformer former secondary coil number of turn ratio.Can use when realizing identical exciting power the excitation winding that sectional area is less after booster tension, thus reduce the volume and weight of magnet exciting coil, save raw material.
