Abstract
The invention provides an anti-shake circuit of a variable pitch motor. The anti-shake circuit of the variable pitch motor comprises a sine comparator circuit, a first trigger which is connected with the sine comparator circuit, a cosine comparator circuit and a second trigger which is connected with the cosine comparator circuit. An output signal of the sine comparator circuit is used as a CLKB signal of the first trigger. An output signal of the cosine comparator circuit is used as a CLKA signal of the second trigger. The first trigger and the second trigger are connected with the same reference voltage. Compared with the prior art, the anti-shake circuit of the variable pitch motor has the advantages that an improved variable pitch motor signal is capable of enabling the variable pitch motor to be completely stable and deserve to be popularized.
Description
Technical field
The present invention relates to a kind of Anti-shaking circuit that becomes the oar motor.
Background technique
Along with non-renewable energy resources face exhausted awkward situation at world wide, for satisfying industrialized production and the human lives is required, people are to the concern of solar energy, wind-force, these renewable energy sourcess of waterpower and utilize day by day and promote.Wherein, wind-power electricity generation is a kind of relatively ripe energy development technology that developed, as the emphasis of China's new energy development strategy.
Wind-driven power generation control system requires to have stronger adaptive capacity to environment.Wind power pitch-controlled system is one of core component of wind-power electricity generation, and Main Function is to change the angle of wind power generating set blade according to the size of wind driven generator output power, guarantees that wind-driven generator output is in rated power.In prior art, the signal that becomes the oar motor may less stable, therefore a signal Anti-shaking circuit need to be arranged.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is to provide a kind of signal Anti-shaking circuit that becomes the precise and stable change oar of oar motor.
Technological scheme of the present invention is achieved in that
A kind of Anti-shaking circuit that becomes the oar motor comprises sinusoidal comparison circuit and connected the first trigger, cosine comparison circuit and connected the second trigger, and the output signal of described sinusoidal comparison circuit is as the CLKB signal of the first trigger; The output signal of described cosine comparison circuit is as the CLKA signal of the second trigger, and described the first trigger and the second trigger are connected in same reference potential.
Compared with prior art, the invention has the beneficial effects as follows: the change oar motor signal of optimization can make and become oar motor complete stability more, is worthy to be popularized.
Description of drawings
Fig. 1 is the schematic diagram that the present invention becomes the Anti-shaking circuit of oar motor.
Embodiment
Mode with example describes the specific embodiment of the present invention with reference to the accompanying drawings.
The present invention becomes the Anti-shaking circuit of oar motor, specifically as shown in Figure 1, comprise sine ratio than circuit U 3A and connected the first trigger, cosine ratio is than circuit U 3B and connected the second trigger, and the output signal of described sinusoidal comparison circuit is as the CLKB signal of the first trigger; The output signal of described cosine comparison circuit is as the CLKA signal of the second trigger, and described the first trigger and the second trigger are connected in same reference potential.
When inserting the zero passage comparison point, because can there be error in the SIN and the COS analogue value that become the output of oar motor, can cause shake and skew that comparison point is inserted.Utilize the phase difference of SIN+ and SIN-comparison signal generation as the CLK signal of the first trigger, go to beat the B phase signals, at this moment B overturns mutually certainly.In like manner, utilize phase difference that the comparison signal of COS+ and COS-produces as the CLK signal of the second trigger, go to beat the A phase signals.So just eliminate the shake of comparison point, reduced simultaneously the climbing time of insertion point rising edge, improved signal accuracy.
Although be the example purpose, the preferred embodiment of the present invention is disclosed, but those of ordinary skill in the art will recognize, in the situation that do not break away from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
