Specific embodiment
As shown in figure 1, a kind of driver for switching reluctance motor, including single-phase 4/4 configuration switches reluctance motor, list
Phase asymmetrical half-bridge formula power inverter and MCU single-chip microcomputers are the total digital controller of core, single-phase 4/4 knot as shown in Fig. 2 to 3
The phase winding 5 in series of concentratred winding 2 in structure switched reluctance motor structure on each salient pole, single-phase asymmetrical half-bridge formula work(
The upper pipe S1 and down tube S2 output ends of rate converter respectively with the phase of phase winding 5 of the single-phase 4/4 configuration switches reluctance motor
Even, when one of upper pipe S1 and down tube S2 (MOSFET or IGBT) shut-offs, the phase winding 5 of switched reluctance motor is powered off.
The rotating shaft 4 of the single-phase 4/4 configuration switches reluctance motor is provided with rotor position detector and phase winding 5 and sets
There is current detector, the position of rotor 3 on rotor position detector detection switch reluctance motor, there is provided the position of rotor 3
Information is by be delivered to that MCU single-chip microcomputers are core after electrical isolation 15V to 5V PT0/PT1 mouthfuls of total digital controller, foundation
Minimum reluctance principle, is PT4 mouthfuls of output winding logical signal of the total digital controller of core by MCU single-chip microcomputers, by leading
Pipe S1 on logical, switch-off power converter, with determine winding 5 open with shut-off, so as to attract rotor 3 to minimum reluctance position side
To rotation：If rotor 3 is in minimum reluctance place value with stator 1, PT4 mouthfuls to pipe S1 outputs low and high level letter on power inverter
Number, after electrical isolation 5V to 15V, pipe S1 shut-offs on control power inverter；If rotor 3 is non-in minimum reluctance with stator 1
During place value, to the level signal of pipe S1 on power inverter, after electrical isolation after 5V to 15V, control power becomes for PT4 mouthfuls of output
Pipe S1 conductings on parallel operation.
The current detector be used for the real-time current of detection switch reluctance motor phase winding 5, by current signal through electrically every
PAD00-PAD03 mouthfuls of the total digital controller that MCU single-chip microcomputers are core is delivered to after 15V to 5V, there is provided current information is complete
Into Current cut control or take corresponding safeguard measure to prevent overcurrent, i.e., by controller PP1 mouthfuls outwards output PWM believe
Number, when controller, outwards output pwm signal be 0, otherwise outwards output pwm signal be 1, pwm signal with
PT4 mouthfuls of output the control signal of pipe S1 on power inverter is done logic phase with that is, when the pwm signal of output is non-zero, and PT4
On mouthful output conducting power converter during the level signal of pipe S1, through electrical isolation 5V to 15V, under just making power inverter
Pipe S2 is turned on.
When the utility model is used, the upper pipe S1 and down tube S2 of power inverter are off state, switched reluctance electric
The rotor 3 of machine is moved first under inertia, and rotor position detector detects the position of rotor 3, and position signalling is sent to
The signal that the total digital controller of MCU compositions is input into according to rotor position detector, judges that stator 1, the relative position of rotor 3 are
No to meet minimum reluctance principle, if meeting, total digital controller exports a level signal so that the upper pipe of power inverter
S1 continues to be held off, and rotor 3 continues rotation under effect of inertia, until deviateing minimum reluctance position；If not meeting, count
Word controller exports a level signal so that the upper pipe S1 of power inverter continues to tend to remain on, now due to electric current
The electric current of detector detection is normal, and digitial controller exports non-zero pwm signal simultaneously, through logic phase and conducting power converter
Down tube S2；The upper pipe S1 of conducting power converter, down tube S2 are simultaneously turned on, and switched reluctance motor phase winding 5 obtains electric, attracts
Rotor 3 rotates to minimum reluctance position；In said process, if excessive abnormal conditions occurs in electric current, the pwm signal for exporting is 0,
Through logic with cannot conducting power converter down tube S2, the phase winding 5 of switched reluctance motor cannot obtain electric all the time；Enter one
The electrical isolation device that step, position signalling and electric signal pass through uses light-coupled isolation chip, voltage conversion function is realized, to prevent
High-low voltage influences each other, and MCU single-chip microcomputers are PA0-PA5 mouthfuls of access keyboard of the total digital controller of core, realize control ginseng
Several given and input, PS0-PS1 mouthfuls of access host computer, realizes the display function of the information such as rotating speed, electric current, voltage.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, although ginseng
The utility model is described in detail according to previous embodiment, for a person skilled in the art, it still can be with
Technical scheme described in foregoing embodiments is modified, or equivalent is carried out to which part technical characteristic.It is all
Within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc. should be included in this practicality
Within new protection domain.
