What this integrated circuit special for controlling switch reluctance motor (chip) adopted is the CMOS production technology of 0.5 μ m, adopts the SOP-28 encapsulation.
Contrast Fig. 2, position signalling is input to the position signalling input module, and the variation of position signalling input module affirmation level provides simultaneously to jump along detecting and indicates after level changes and keeps surpassing 16 clock cycle.Three cycle rate counters count respectively jump on twice of each position signalling along between clock number, obtain the position signalling periodic quantity.Because cycle rate counter is respectively to three position signalling countings, so as lacking a position signalling even having only a position signalling, also can accurately obtain the position signalling periodic quantity.The periodic quantity that obtains is pressed in the fifo queue of cycle mean value calculation, through obtaining the average period of position signalling after average.Angle time-delay computing module and conducting time-delay computing module are opened time-delay count value and conducting time-delay count value according to position signalling CITAx, CITAD and position signalling cycle mean value calculation motor.Selecting the triggering source of three-phase angle output with SELA, SELB, SELC, can be that three position signallings are jumped up and down along in these 6 signals any.Load and open the time-delay count value and subtract counting when back angle control output module appears in triggering signal, load the conducting conducting delay counter of delaying time simultaneously and cushion to opening the delay counter work.Load data into the conducting delay counter and make to subtract counting and put simultaneously to export and open logic from conducting delay counter buffering when opening the time-delay back that count down to 0.In conducting delay counter counting process,, do not influence the operating state and the output state of conducting delay counter by same program work as triggering signal occurring.When conducting time-delay counting reduced to 0, logic was closed in output.If do not open delay counter and reduce at 0 o'clock, then load new conducting time-delay count value and cover original value and keep output to open logic simultaneously to 0 at conducting time-delay counting.
Angle control signal calculating turns to the sequence detection motor that takes place to take place by three position signallings in the module, thinks that PS, QS, three position signallings of RS appear as forward in proper order, otherwise are reverse.If have a position signalling to break down then can't detect correct turning to,
After the cycle, mean value calculation obtained the result, the revolution speed calculating device removed 4 times cycle mean value with the rotating speed coefficient CALC in the parameter list and obtains tachometer value and be kept among the sheet internal state register STATUS.Overflow or cycle count value when overflowing when the too little calculating of cycle mean value, all that tachometer value is set are the invalid tachometer value of 1 expression.
Contrast Fig. 3, the special-purpose control integrated circuit of switched reluctance machines (chip) can be directly used in the drive controlling of power circuit for 6 control signals of threephase switch reluctance motor controller output.Aup, Adn be corresponding A phase top tube and down tube drive controlling respectively, and Bup, Bdn be corresponding B phase top tube and down tube drive controlling respectively, and Cup, Cdn be corresponding C phase top tube and down tube drive controlling respectively.It is 24mA that these 6 pins all are out to leak the design maximum current, can be directly used in to drive the device that optocoupler etc. has big current requirements.The LOGIC pin is used to set output logic, is the corresponding conducting power tube of high level or opposite.The corresponding power tube conducting of low level during LOGIC=1, high level turn-offs.The corresponding power tube of low level turn-offs the low level conducting during opposite LOGIC=0.
In the signal synthesis output module, the control signal of some control modes that the special-purpose control integrated circuit of switched reluctance machines will be used always combines.Can set parameters such as OUTSEL, CHOPST and PWMEN by the control mode that will adopt.OUTSEL selected angle signal occurring mode, four kinds of producing methods: angle calculation output (00b), position signalling directly export (01b), the anti-phase output of position signalling (10b) manually export (11b).Angle calculation output refers to interior angle and resolves module according to the angle control signal that CITAx, CITAD and CITASET set point take place, and is usually used in the angle position control mode; Position signalling directly output and the anti-phase output of position signalling is that to work as motor speed very low, and interior angle is resolved when module can't be calculated output angle and adopted, and is generally used for starting process; Manually output refers to according to the output of parameter DSETx set-point, and on off state and position signalling that the value of change DSETx has also just changed power tube have nothing to do.For the motor of self-starting difficulty, can inquire about STUP among the STATUS～STUR value at a starting section single-chip microcomputer and obtain current position signal, and as according to which phase of decision conducting or which turn-offs realize smooth start mutually.
Current chopping time-delay, two step commutations also integrated in the special-purpose control integrated circuit of switched reluctance machines are delayed time, these assist control means commonly used of PWM.By setting the CHOPST decision, with four kinds of chopping ways: any mode of cut two-tube (00b), cut pipe (01b), cut down pipe (10b), cutting in the single tube (11b) in turn is mutually comprehensive with the angle output signal with these signals.Cut auxiliary control signal when two-tube and directly be added on the output signal of pipe up and down, pipe is opened simultaneously or is closed simultaneously up and down.Auxiliary control signal only acts on the pipe output signal when cutting pipe.Auxiliary control signal only acts on down the pipe output signal when cutting down pipe equally.Cut single tube in turn and refer to auxiliary signal and change the output signal act on top tube and down tube in turn, can make the basic identical working life that helps prolonging power tube of condition of work of pipe up and down like this by on off state.
SPI communication management module, by the SPI communication interface of the special-purpose control integrated circuit of switched reluctance machines,
All Control Parameter of addressable its inside.The special-purpose control integrated circuit of switched reluctance machines is as slave unit work, and its SPI communication is defined in jumps on the synchronised clock along data bit is shifted out, and following jumping is along moving into data bit, and each data is 16, and peak transfer rate is fclk/4.
Contrast Fig. 4, SPI communication management module is relevant SCK, MOSI, four pins of MISO, SPIEN, and the SCK pin is the synchronised clock input pin, and maximum SCK frequency is fclk/4.MOSI is the data input pin, and SCK jumps along data are moved into down.MISO is the data output pin, and the last jumping of SCK is along shifting out data, and SPIEN is a SPI function strobe pin,
Contrast Fig. 2 has two identical pwm signal generators in the special-purpose control integrated circuit, first pwm signal generator output DAPWM, and the second pwm signal generator uses in inside.The pwm signal generator has two kinds of mode of operations singly to increase pattern and increase and decrease pattern.Singly increasing under the pattern cycle rate counter is added to after the cycle set point clear 0 from 0 and adds up again.Cycle rate counter is decremented to 0 after being added to the cycle set point from 0 again under the increase and decrease pattern.Under obvious two kinds of patterns under the identical parameters condition, duty ratio equates and singly increases frequency under the pattern is under the increase and decrease pattern 2 times.Increase and decrease pattern output waveform left-right symmetric, so its harmonic content is less.Two set points of following cycle of pattern and conducting width only load when cycle rate counter is 0.
Contrast Fig. 5, chopping signal CHOPA, CHOPB and the CHOPC of the corresponding three-phase of chopping signal generation module difference in the special-purpose control integrated circuit of switched reluctance machines.CHOPx loads copped wave delay adjustments value during for high level, and chopping signal generation module output low level requires output copped wave.Delay counter begins to successively decrease after CHOPx is by high step-down, reduces to 0 back output high level and finishes the copped wave time-delay.Therefore the time span of actual copped wave is greater than the corresponding time of copped wave time-delay count value of setting.Be only copped wave delay adjustments value as shown in the figure from T1 to the T2 correspondence, T0 is actual copped wave time span to T2.Copped wave delay adjustments value loads when chopping signal occurs.
Contrast Fig. 2, the special-purpose control integrated circuit of switched reluctance machines provides three tunnel faults input ERR0, ERR1 and ERR2, low level fault.When becoming low level by high level on the pin, the fault-signal processing module latchs this signal, and output 6 road power tube control signals are turn-offed.After leg signal was recovered by malfunction, the fault-signal processing module still was in the fault hold mode, and control signal still can not be exported.To from the malfunction latch mode, recover, must send CLRERR instruction removing to chip by the SPI interface and latch.Another kind of situation, malfunction exist all the time and chip receives the CLRERR instruction and removes and latch, and at this moment chip still keeps not exporting, in case chip can be exported control signal but malfunction is recovered at once.Malfunction and the malfunction that latchs can read the STATUS parameter and obtain.
Fault latch and input clock are irrelevant, still can protect power device by latch fault even input clock breaks down.But the SPI communication must have correct clock input to guarantee, removes fault latch otherwise can't receive the CLRERR instruction, will no longer export control signal after breaking down.
Special-purpose control integrated circuit (chip) feature of switched reluctance machines: can realize angle control; current chopping control; voltage pwm control; the commutation control of two steps; the angle controlled function; can handle position signalling (the 10MHz clock frequency of 10kHz; the processing accuracy one thousandth position signalling cycle); operating voltage 2.7V is to 5.5V; multiple current chopping form; copped wave time-delay time-delay able to programme; (the one tunnel is exportable) takes place in two-way PWM able to programme; two step commutation delay times able to programme; the input of 3 road power guard signals, the output mixed logic is optional, and control signal is opened Lou output; maximum 24mA irritates electric current, SPI communication interface.
