    • PURPOSE: A method and apparatus for controlling the average voltage applied to a phase winding of a reluctance machine during a period of current increase, controlling the current when a desired current is reached, and controlling the voltage applied during a period of current decrease, to improve machine efficiency and thereby reduce acoustical noise produced by the machine, and unwanted vibration. CONSTITUTION: The apparatus comprises circuitry and associated elements which are operable to switch the phase winding into circuits which apply either a positive DC voltage, a zero voltage, or a negative DC voltage, to increase, maintain, or decrease the current in the winding. The timing and the rate of the switching is controlled as a function of the angular position and speed of a rotor of a reluctance machine (20), the torque output of the machine, and the desired speed or torque. The calculation of the appropriate duty cycle for the specific operating conditions of the reluctance machine (20) controls the net average voltage applied, has been found to reduce abrupt changes in the current. This reduction correlates into reduced abrupt changes in the magnetic flux, resulting in reduced acoustic noise and unwanted vibration.

    • PURPOSE: A variable generating voltage converter based switched reluctance generator drive system is provided to prevent the sharp decline of current in the low and medium speed range and the excessive increase of current in the high speed range by controlling generating voltage regardless of excitation voltage. CONSTITUTION: A proportional plus integral action (PI) power controller (110) produces a conductive angle by proportionally integrating power. An average value calculation unit (120) produces an electricity average power value for the direct current voltage and direct current of a power converter (140). An angular position controller (130) calculates the state of a phase switch by controlling an angular position according to the sense of heat and the position of a rotor which are produced from the difference of an off angle and a conduction angle. The power converter (140) drives a switched reluctance generator at a variable speed by using variable speed generating voltage according to the state of a switching element and a phase switch. A current output unit (150) calculates the current of an off-angle position from generating voltage which is output from the position of the rotor and the power converter.

    • A switched reluctance generator is controlled such that flux growth in a phase winding (10,12,14) occurs at a faster rate during the initial part of the phase inductance cycle and at a second, slower rate during the subsequent part of the phase inductance cycle. The difference between flux growth and decay may be achieved either by applying different voltages during the two parts of the phase inductance cycle or by applying the same voltage over only part of the phase winding during the initial part of the phase inductance cycle and then applying that voltage across the phase winding thereafter. It is advantageous to make the increase in flux more rapid than its decay because minimising the length of time that the flux is present while the phase inductance is rising will minimise the production of unwanted (motoring) torque.
    • 控制开关磁阻发电机,使得相绕组(10,12,14)中的通量增长在相电感周期的初始部分期间以更快的速率发生,并且在相电感的后续部分期间以第二较慢速率发生 周期。 通量增长和衰减之间的差异可以通过在相电感周期的两个部分期间施加不同的电压或通过在相电感周期的初始部分期间在相绕组的一部分上施加相同的电压来实现, 之后的相绕组两端的电压。 使通量的增加比其衰减更快是有利的,因为最小化存在通量的时间长度而相电感上升将最小化不想要的(电动)转矩的产生。 <图像>

    • PURPOSE: A switched reluctance drive is provided to intermittently operate a drive of limited capacity on a bus-bar, without generating significant voltage disturbance. CONSTITUTION: A switched reluctance drive comprises a first voltage source(V1) and a first capacitor(25) connected across a first DC link(26,27), and a second voltage source(V2) and a second capacitor(29) connected across a second DC link. The first and second DC links are shared a common negative line(27). Connected to a positive line(26) of the first DC link is a first switch(21) that is connected to the top of a winding(16), which is in turn connected at its lower end to a second switch(22) that is connected to the common negative line. Connected between the top of the winding(16) and the negative line is a diode(24), which is operable to conduct current from the negative line towards the winding(16). Connected between the top of the winding(16) and a positive line of the second DC link is a third switch(28). Between the bottom of the winding(16) and the positive line of the second DC bus is a diode(23) that is connected so as to conduct current from the winding(16) to the second DC bus. In this way, the diode(23) provides an energy return path between the winding(16) and the second voltage source(V2).
