Electricity.
Counter electromotive force zero passage is monitored, and is used for gathering and monitoring counter electromotive force of motor zero-acrross ing moment, closed loop regulation single-chip microcomputer 11
Output SPWM pulse, realizes motor in synchrony gradually.
Dynamicer 8 is one and carries self-oscillatory timeout mechanism, and this unit is bridged to two-way commutation half-bridge cells 5
And between single-chip microcomputer 11, bear two-way commutation half-bridge cells 5 and main line SPWM manipulator 6, the duty that once time-out is forced shutdown
Can, and to single-chip microcomputer 11, this unit acts also as more reliable power down formula " house dog ".
High pressure monitor 9, for power voltage+VP and-VP are carried out A/D monitoring, to overvoltage or under-voltage warn, and directly
Instruct frequency conversion and pressure regulation.
Crossing stream sampling unit 10, monitoring motor is because crossing stream during stuck or overload.
Tip element 13, including buzzer and light emitting diode, during for pointing out ruuning situation and the exception of whole device
Acousto-optic warn.
This motor circuit uses transformerless without inductor design, modulates SPWM on main line, and delayed closed loop adjusts；Overvoltage,
Crossing and flow biphase monitoring, Dynamic Execution, numerous audible and visual alarm, it is ensured that the highest motor drive efficiency, components and parts all use
Natural heat dissipation, does not has heaviness, thick big, expensive, transformator that can not be integrated and an inductance, the existing very high reliability of this motor circuit and
Safety, conversion efficiency is the highest.
Workflow: after civil power powers on, controls power supply 2 and produces+5.6V the running voltage of single-chip microcomputer 11, and piggybacking dynamically controls
Device 8 loads to single-chip microcomputer 11, and after single-chip microcomputer 11 electrification reset, timing scan dynamic driver 8 Enable Pin completes power supply bootstrapping；Cross
Zero monitor 1 civil power zero-acrross ing moment twice a week produce interrupt, no-voltage open controlled rectifier unit 3 without surge produce ±
Power power-supply+the Vp and-Vp of about 310V；When short circuit commissioning cut-off point unit 4, forceful electric power+Vp and-Vp will be loaded into two-way commutation
On half-bridge cells 5, and by dynamicer 8 in accordance with the order of single-chip microcomputer 11, alternately open down tube on half-bridge, DC voltage
It is transformed into bipolarity alternating-current pulse, then is modulated into two-way through the SPWM main line manipulator 6 of rear end and differs key player on a team's alternating current of 90 °,
Through simple smooth, load and form rotating excitation field driving electric machine rotation to monophase machine 12.
Reference Fig. 2, in figure ± 310V high pressure, it is civil power 220V to be exchanged positively and negatively halfwave rectifier obtain detection peak
Value, either Q1 or Q2 conducting, another is not turned on pipe all by withstanding up to the pressure drop of volt more than 600, in order to prevent two pipes
Punch-through failure, controls power supply 2 and limits energy power supply for electric capacity, utilize the capacitive reactance compression power consumption of electric capacity.
With reference to Fig. 3, this figure is that the present invention controls power supply 2, controlled rectifier 3 and crosses stream sampling unit 10 3 unit integration
Side circuit, circuit high order end is for controlling power supply 2, by electric capacity C6 limit energy, resistance R4 peak clipping, stabilivolt clamper, diode rectification
Produce+5.6V single-chip microcomputer 11 running voltage and+Vp+18V and the control gate driving voltage of-Vp+18V floating, the wherein+Vp of upper end
+ 18V flash driving voltage also wants boosted generation；Bidirectional triode thyristor Q4, by zero cross fired, coordinates D10 and D11 halfwave rectifier
Constitute controlled rectifier 3, C11 and C12 produces+Vp and-Vp power voltage；Cross stream sampling unit 11 to be completed electric current by R9 and adopt
Sample, the padded decision threshold of R12 and R11 dividing potential drop improves current sample sensitivity, R13 and C13 releives electric current moment surge, when because of mistake
Stream R9 burns, and red light emitting diodes D17 will light and directly indicate trouble point, and D17 is played reverse protection effect by D52, has R14
High resistant blocks and prevents the high-pressure energy on C13 from directly leaking into single-chip microcomputer 11 inside.
With reference to Fig. 4, this figure is the driving simplification figure of two-way half-bridge reversing unit, because two-way circuit is just the same, so
Have only to a road is individually analyzed.In figure, the grid source control voltage U2 of down tube Q13 of half-bridge is directly driven by-VP+18V, but right
The driving of upper pipe needs to convert, because after Q13 conducting, upper pipe goes Q12 source potential to be-Vp, and drive circuit must be this
Individual negative high voltage blocks to fall.When D53 just blocks Q13 conducting-Vp high pressure on draw, D52 is then repositioned onto VP+18V on+Vp,
Just differing 90 ° of phase angles between two-way half-bridge break-make, D51 intercepts and opens the respective charging interval to storage capacitor C25.Upper pipe Q12
A pair of left side high pressure PNP pipe Q10 and Q11 pipe left floating flash driving voltage for conversion, although it should be noted that total system
Altogether, but still need configuration high-speed photoelectrical coupler to the huge drop mating between strong and weak electricity.
