Abstract
The utility model discloses a kind of inversion systems, it includes sequentially connected power supply, prime driving, the driving of prime boost power pipe, rear class, rear class inverter power tube and output unit, it further comprises micro-control unit, and the micro-control unit is connect respectively with power supply, output unit, prime drives and rear class is drivingly connected.The utility model is sampled in crest location, but is not made any adjustments at this moment, but does the adjustment of modulation degree again until 180 degree, and therefore, 90 degree of crest location is smoother, and output is reliable and stable.
Description
Technical field
The utility model belongs to inverter apparatus technical field, and in particular to a kind of inversion system.
Background technology
Inverter is sampled using each cycle, and adjusts modulation degree, achievees the purpose that stablize output.Traditional inverter is in wave
Peak position samples, and adjusts modulation degree in crest location, can thus generate the tear phenomenon of crest location.
Utility model content
The purpose of this utility model is to provide a kind of inversion system, solves existing inverter and is torn in crest location
The phenomenon that.
Technical solution is used by the utility model：
A kind of inversion system, including sequentially connected power supply, prime driving, prime boost power pipe, rear class driving, after
Grade inverter power tube and output unit, further comprises micro-control unit, the micro-control unit respectively with power supply, output
Unit connection, prime driving and rear class are drivingly connected.
The utility model is also characterized by
Further comprise filter unit, the filter unit is arranged between rear class inverter power tube and output unit.
The micro-control unit of stating is HYM8F028C6.
The prime driving is using MIC4452.
The rear class driving is using IR2110S.
The filter unit includes the first inductance, the second inductance and capacitance, and the capacitance is arranged on the first inductance and the
Between two inductance
Compared with prior art, when the utility model is used, it samples in crest location, but does not make any adjustments at this moment,
But do the adjustment of modulation degree again until 180 degree, therefore, 90 degree of crest location is smoother, and output is reliable and stable.
Description of the drawings
Fig. 1 is that the utility model embodiment provides a kind of system block diagram of inversion system；
Fig. 2 is the circuit diagram that the utility model embodiment provides that prime drives in a kind of inversion system；
Fig. 3 is that the utility model embodiment provides a kind of operating diagram of inversion system.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The utility model embodiment provides a kind of inversion system, as shown in Figure 1, it includes sequentially connected power supply 1, prime
Driving 2, prime boost power pipe 3, rear class driving 4, rear class inverter power tube 5 and output unit 6, further comprise micro-control
Unit 7 processed, micro-control unit 7 is connect respectively with power supply 1, output unit 6,4 connection of prime driving 2 and rear class driving.
Further comprise filter unit 8, filter unit 8 is arranged between rear class inverter power tube 5 and output unit 6, filter
Wave unit 8 includes the first inductance, the second inductance and capacitance, and capacitance is arranged between the first inductance and the second inductance, the first electricity
Sense and the second inductance use the copper wire of 1.2MM, coiling inductance value 1.5mH, capacitance selection 10UF.
Micro-control unit 7 is HYM8F028C6, clock frequency 60MHz, is internally integrated 2 tunnel amplifiers, 1 road comparator, 12
AD, 3 16, tunnel complementary output PWM, so, realize that inversion greatly reduces generation using the 2 tunnel complementation PWM of HYM8F028C6
Code writes difficulty, improves development efficiency.
As shown in Fig. 2, prime driving 2, using MIC4452, MIC4452 driving forces are strong, and up to 12A, output is stablized.
Rear class driving 4 has light-coupled isolation (small) concurrently using IR2110S, the IR2110 drivers of IR companies of U.S. production
The advantages of with electromagnetic isolation (speed is fast) is the first choice of driving element in middle low power converting means.
As shown in figure 3, inversion system in 90 degree of each period, i.e., after crest location sampling, is adjusted not immediately and is adjusted
System, but modulation degree is adjusted again until 180 degree, thus effectively avoid the phenomenon that wave crest is torn.
Using the above scheme, compared with prior art, when the utility model is used, sampled in crest location, but at this moment
It does not make any adjustments, but does the adjustment of modulation degree again until 180 degree, therefore, 90 degree of crest location is smoother, output
It is reliable and stable.
The preferable specific embodiment of the above, only the utility model, but the scope of protection of the utility model is not
This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, can be readily occurred in
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
It is subject to the protection scope in claims.
