TW202318759A - Dual power generator system provided with a stator core and a rotor core - Google Patents

Abstract

The present invention relates to a dual power generator system, and more particularly to a generator with a stator core and a rotor core. The rotor core is provided with a plurality of equally-divided magnetic pole windings and coil windings. The stator core is provided with two alternating current supply units separated from each other. The directions of the coil windings of the two alternating current supply units are opposite, one is forward-winding and the other is reverse-winding without interfering with each other. The two alternating current supply units are provided with two bridge rectifiers, such that after the high-current low-voltage alternating current is converted into direct current, charging on two batteries is performed. One of the battery converts low-voltage direct current into high-voltage alternating current through an inverter, and then provides the alternating current to external loads. The other battery supplies direct current power to the motor for operation, which can effectively avoid power loss during conversion.

Description

Dual Power Generator System

The dual-power generator system of the present invention is mainly applied to the technology that a generator can simultaneously output high-current and low-voltage power sources on both sides, so that the generator can charge the battery and directly use external loads at the same time when the generator is running.

According to the current AC synchronous generator, it can be designed as a generator that generates single-phase or multi-phase AC voltage according to the number of output phases of the stator winding. How a single phase alternator works. When the magnet rotates, a sine wave AC electromotive force e is generated in the two stator windings. The power source that generates the electromotive force is called a phase, and this generator uses AC supplied by a single phase and two wires, called single-phase AC, and this power distribution method is called a single-phase two-wire system. In addition, the traditional common generator is three-phase 220V, and its outgoing wires are three, plus a grounding wire. It also adopts single power output mode.

However, the above-mentioned conventional single-phase two-wire generators have the problem of conversion power loss when AC is converted to DC, and then converted from DC to AC.

The inventor is currently engaged in the manufacture and design of related products, has accumulated many years of practical experience and experience, and aimed at the existing problems and shortcomings of traditional common single-phase two-wire generators Lost, actively invested in the spirit of innovation and improvement, completed the dual power generator system.

The technical means applied in the invention to solve the problem and the effect compared with the prior art are: the generator is provided with a stator core and a rotor core, and the rotor core is provided with a plurality of equally divided magnetic pole windings and coil windings. The iron core is isolated and provided with two AC power supply units. The winding directions of the coil windings of the two AC power supply units are opposite, one is forward-winding and the other is reverse-winding. A bridge rectifier is used to convert high-current and low-voltage alternating current into direct current, and then charge two batteries. One battery converts low-voltage direct current into high-voltage alternating current through an inverter, and then provides alternating current to external loads. The other battery supplies DC power to the motor to run, which can effectively avoid power loss during conversion, and has an increase in efficacy, which is its main purpose.
