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...
Embodiment 2
[0088] In another small-scale wind power generation embodiment using the present invention, based on the microcomputer-controlled phase-shifting pulse trigger voltage stabilizing device described in Embodiment 1, the wind energy is converted into three-phase alternating current through a permanent magnet wind generator. After rectifying and stabilizing the voltage output of the device of the present invention, and then passing through the inverter for inverting, the wind energy can be converted into electric energy.
[0089] Using the wind power generator manufactured in this embodiment, the conversion efficiency of wind energy and electric energy can generally be increased to 10%.
