    • A speed controller for a DC motor includes a semiconductor switching device connected in series with it in a DC power circuit. The switching circuit is turned on and off with a duty ratio variable as a function of motor load. A time constant circuit including a capacitor is connected in parallel with the switching device to develop a voltage which is compared with a reference variable between high and low levels in response to the exceedance of the varaible reference. The switching device is turned on when the voltage developed by the capacitor is higher than the lower reference voltage to energize the motor, and is turned off when the capacitor voltage is lower than the higher reference voltage to de-energize the motor. The on-duty period of the motor is variable as a function of a motor-load representative voltage developed in the switching device during its turn-on period and the off-duty period is variable as a function of a counter-electromotive force generated in the motor as inversely proportional to motor load.

    • An improved H-bridge power amplifier for controllably driving a dc motor is presented. The motor is connected in the center of the H-bridge in conventional manner. The H-bridge includes a current sense resistor placed between the power supply and a common tie point of the upper transistors of the bridge. Free wheeling diodes are connected from the motor directly to the power supply. This arrangement allows current to flow through the current sense resistor only when one of the upper transistors is on. The power amplifier is operated by selecting an appropriate pair of upper and lower transistors on opposite sides of the bridge so as to cause the current to flow through the motor in a desired direction. Both the upper and lower transistors of the selected pair are held ON until the current as sensed in the current sense resistor equals or exceeds a specified value, typically a desired current level. When this occurs, the upper transistor is turned OFF for a fixed off-time period, during which time the lower transistor is maintained ON. The motor current thereby decays through a path comprising the ON lower transistor, one of the free wheeling diodes, and the motor, which decay path significantly reduces the ripple associated with the motor current. At the end of the fixed off-time, the upper transistor is turned ON, and the process repeats itself. If braking is desired to slow the motor down, a plug inhibit mode is enabled wherein the lower transistor is turned off and the upper transistor is alternately turned ON and OFF.
    • 提出了一种用于可控驱动直流电动机的改进的H桥功率放大器。 电机以常规方式连接在H桥的中心。 H桥包括放置在电源和桥的上部晶体管的公共连接点之间的电流感测电阻器。 自由轮二极管从电机直接连接到电源。 这种布置允许电流仅在上部晶体管中的一个导通时才流过电流检测电阻器。 功率放大器通过在桥的相对侧上选择合适的一对上,下晶体管来操作,以使电流沿着所需方向流过电动机。 所选择的对中的上和下晶体管都保持ON,直到在电流检测电阻器中检测到的电流等于或超过指定值,通常为期望的电流电平。 当这种情况发生时,上限晶体管关断一段固定的关闭时间,在此期间,下部晶体管保持ON。 电动机电流因此通过包括ON下晶体管,续流二极管之一和电动机的路径衰减,该衰减路径显着地减小了与电动机电流相关联的纹波。 在固定关断时间结束时,上部晶体管导通,该过程重复。 如果需要制动以使电机减速,则可以启用插头禁止模式,其中下部晶体管截止并且上部晶体管交替地导通和截止。
