    • A rising saw tooth signal generating circuit generates a rising saw tooth signal having a constant amplitude and a constant period which corresponds to a frequency being slightly higher than the human audible frequency range. The rising saw tooth signal generating circuit also generates a binary signal which generates a reference chopping timing synchronizing with the rising saw tooth signal. The rising saw tooth signal is inverted and a descending saw tooth signal is generated. The descending saw tooth signal is added to the reference current signal and a binary signal is generated by the result of the comparison between the addition signal and the actual current signal. A flip-flop generates a signal which reaches a low level whenever the binary signal is descended and which reaches a high level whenever the reference chopping timing comes. A further binary signal which moves to the high level at the feeding of the current and the signal are supplied to the AND gate. The output signal of the AND gate and the signal is supplied to an AND gate and a binary signal for driving a switching element is obtained.
    • 上升的锯齿信号发生电路产生具有恒定振幅和恒定周期的上升锯齿信号,该恒定周期对应于略高于人类可听频率范围的频率。 上升锯齿信号发生电路还产生二进制信号,该二进制信号产生与上升锯齿信号同步的参考斩波定时。 上升的锯齿信号被反转,产生锯齿信号的下降。 下降的锯齿信号被加到参考电流信号中,并且通过加法信号和实际电流信号之间的比较结果产生二进制信号。 触发器产生每当二进制信号下降时达到低电平并且每当参考斩波定时到达时达到高电平的信号。 在馈电电流和信号时移动到高电平的另一个二进制信号被提供给与门。 与门和信号的输出信号被提供给与门,并获得用于驱动开关元件的二进制信号。

    • The chopping power controller reduces switching error due to the noise in the current detected signal. The chopping power controller includes a switching member (18a) for supplying power to an electric load (1a) and a current sensor (2) for detecting electric current flowing through the electric load (1a). The detected electric current is compared by a comparator (16a, 30a) to a target value. The output from the comparator is supplied to a filter (23) for outputting identical signal (k) as the comparator (16a, 30a) after the comparator (16a, 30a) keeps the same level signal for a period of time. The switching member (18a) is turned off when the detected electric current continuously exceeds the target value for the period of time set at the filter (23). The filter (23) may removes the noise which has a shorter period than that of the filter (23). In other words, the filter (23) removes high frequency noise from the comparator (16a, 30a) in order to turn off the switching member (18a) accurately. Therefore, less switching error is generated due to high frequency noise.
    • 斩波功率控制器可减少由于电流检测信号中的噪声引起的开关误差。 斩波功率控制器包括用于向电负载(1a)供电的开关元件(18a)和用于检测流过电负载(1a)的电流的电流传感器(2)。 检测出的电流通过比较器(16a,30a)与目标值进行比较。 在比较器(16a,30a)保持相同电平信号一段时间后,比较器的输出被提供给滤波器(23),用于输出与比较器(16a,30a)相同的信号(k)。 当检测到的电流连续超过设定在过滤器(23)的时间段的目标值时,切换部件(18a)被断开。 过滤器(23)可以去除具有比过滤器(23)的周期更短的周期的噪声。 换句话说,滤波器(23)从比较器(16a,30a)去除高频噪声,以便精确地关断开关元件(18a)。 因此,由于高频噪声而产生较少的开关误差。

    • A chopping energization control device is made up of a first switching element interposed between one end of a load and one terminal of a power supply, a second switching element interposed between the other end of the load and the other terminal of the power supply, a signal generation device for generating an energization indication signal which makes the first switching element and the second switching element conductive in order to establish a chopping energization control of the load, and a control device for giving a delay, in response to the energization indication signal, between when the first switching element is made to be conductive and when the second switching element is made to be conductive. The control device has a changeover device for establishing, whenever a set time duration elapses, that an earlier conductive switching element and a later conductive switching element are interchanged with each other where the one of the first switching element and the second switching element and the other are defined as the earlier conductive switching element and the later conductive switching element, respectively.

    • The system energizes an SR motor with a current of a level which corresponds to a target rotational speed and a target torque of a rotor. The system includes an energization pattern generator which is intended to provide a smooth rotation of the rotor. The system also includes a direction of rotation detector circuit which detects an oscillation of the rotor in a peripheral direction and a compensator which corrects an energization level in synchronism with the oscillation, thereby suppressing an oscillation of the rotor in the peripheral direction. Finally, the system includes another compensator which corrects an energization level to nullify a deviation of an actual rotational speed with respect to the target rotational speed of the rotor.
