Description
Technical Field
The invention relates to a voltage regulator, in particular to a 24V permanent magnet synchronous generator voltage regulator.
Background
In a dc generator, an excitation method for generating a rotating magnetic field by a dc current is called current excitation. If permanent magnets are used instead of current excitation to produce a rotating magnetic field, such a generator is called a permanent magnet generator. The adoption of the permanent magnet rotor structure enables the internal structure design of the generator to be arranged compactly, and the volume and the weight to be greatly reduced. The simplification of the structure of the permanent magnet rotor also reduces the rotational inertia of the rotor, increases the practical rotating speed and achieves a high value of specific power (namely the ratio of power to volume). Under the condition of good medium and low speed power generation performance and the same power grade, the output power of the permanent magnet generator is doubled when the permanent magnet generator is idling.
The permanent magnet generator has the advantages of small volume, low loss, high efficiency and the like, and the research on the permanent magnet generator is very necessary nowadays when the energy conservation and the environmental protection are increasingly emphasized. Brushless is realized in many cases, and therefore, it is often used for small-sized and micro-sized generators.
The magnetic field of the permanent magnet generator can be maintained without external energy after being manufactured, but the magnetic field is difficult to adjust and control from the outside. These limit the range of applications of permanent magnet generators. However, with the rapid development of control technologies of power electronic devices such as MOSFET and IGBTT, it is possible to control only the motor output without magnetic field control in application of a permanent magnet generator. The permanent magnet generator has new application opportunity and development in various fields due to the combination of three new technologies, namely, power electronic devices and microcomputer control.
The existing voltage regulation technology of the permanent magnet generator adopts a direct switch to control a rectifier bridge, is coarse regulation control and is mainly suitable for a high-power generator, has the problems of large voltage fluctuation and the like of a small micro generator below 500W, and can not realize accurate regulation and control of voltage.
