摘要： The invention relates to a supply circuit arranged to be connected to a power supply, a rechargeable buffer for electric energy and to an electric motor, comprising
• a power line arranged to connect an output of the power supply to an input of a motor drive circuit wherein the motor drive circuit is arranged to lift the voltage supplied on the input using regenerated power of the motor in a regeneration mode of the supply circuit; and
• a control unit.
The control unit is arranged to measure the voltage on the power line using a sensor circuit.
The supply circuit comprises a buffer connection line to connect the power line to the rechargeable buffer comprising a controllable switching device (12) arranged to be controlled by the control unit, wherein the control unit is arranged to compare the measured voltage with a threshold voltage and to operate the controllable switching device in a conductive state upon concluding that the measured voltage is higher than the threshold voltage.
The power line comprises a connection for a further load arranged to be supplied by either the power supply or by the motor.摘要翻译： 供电电路技术领域本发明涉及一种供电电路，该供电电路被布置成连接到电源，用于电能的可再充电缓冲器和电动机，包括：电力线，其被布置为将电力供应器的输出连接到电动机驱动电路的输入 其中所述电动机驱动电路被布置为在所述供电电路的再生模式中使用所述电动机的再生电力来提供在所述输入端上供应的电压; 和•一个控制单元。 控制单元布置成使用传感器电路来测量电力线上的电压。 供电电路包括用于将电力线连接到可再充电缓冲器的缓冲连接线，该缓冲连接线包括布置成由控制单元控制的可控开关装置（12），其中控制单元布置成将测量的电压与阈值电压进行比较，以及 在断定所测量的电压高于阈值电压时，操作可控开关器件处于导通状态。 电力线包括用于另外的负载的连接，该另外的负载布置成由电源或由电机提供。

摘要： A PWM speed regulating apparatus for a DC elevator comprises a rectifier and filter (1), voltage suppressor (2), chopper voltage regulator (3), system controller (4) and a driving protector (5). The speed of DC motor is regulated by a pulse width modulating mode so that the current of the motor is maintained continuously and the ripple of current and torque is lower, and which ensures a good riding quality and a high floor arrival accuracy.
