Embodiment 1

[0069] The circuit of this embodiment is realized like this:

[0070] The circuit of the microcomputer-controlled phase-shifting pulse triggering voltage stabilizing module includes a working power supply circuit, a motor three-phase voltage frequency acquisition circuit, a voltage stabilizing and feedback setting circuit, a single-chip microcomputer circuit and a thyristor driving circuit. The function and circuit principle of each part of the circuit are realized in this way.

[0071] The main function of the working power supply circuit is to provide a high-precision and stable 3.3V power supply to the microcomputer-controlled phase-shift pulse trigger voltage regulator module. The working power supply circuit adopts DC-DC conversion module LM1575 with wide range voltage input (4.75V~60V) to adapt to permanent magnet generators with different voltage output levels (such as 14V, 28V, 36V, etc.), and the realization of the circuit as attached Figure 4 As shown, the three-p...

Abstract

The microcomputer controlled phase shift triggered voltage stabilizer for permanent magnet generator includes circuit of operational power supply, circuit for collecting three-phase voltage and frequency of motor, setting circuit for voltage regulation and feedback, circuit of single chip, and thyristor drive circuit etc. Using calculation function of single chip implements closed loop control of software, and turns on three-phase shift triggering pulse to trigger thyristor. Built in or configured in permanent magnet generator, voltage stabilizer outputs stable DC voltage. Self-starting mode is adopted in the invention. Thus, generator can output stable voltage without need of external voltage so as to prevent phenomena of no outputted voltage if no external DC voltage (for ex. in excitation type motor) from occurring. Advantages are: raised reliability, reduced maintenance work, good load characteristic, quick adjustment and high precision of output voltage.

Description

technical field [0001] The invention relates to a voltage stabilizing output device of a generator, in particular to a microcomputer-controlled phase-shifting pulse trigger voltage stabilizing device of a permanent magnet generator. Background technique [0002] At present, the generator adopts an excitation type alternator, and its voltage regulation mode is to adjust the magnetic flux φ of the rotor excitation winding to realize the adjustment of the three-phase voltage output by the generator. The motor phase voltage E e1 The relationship with the magnetic flux φ of the excitation winding is: [0003] E. e1 =4.44NK n1 fφ (1) [0004] In the formula, E e1 ——Motor phase voltage; N——Motor winding number; K n1 ——Motor winding coefficient f——Motive force frequency; φ——Excitation winding flux [0005] From formula (1), we can see that the motor phase voltage E e1 It is proportional to the magnetic flux φ of the excitation winding and the rotational speed. As the rotation...
