    • In response to a system-off instruction, the drive system control technique of the invention controls individual motors of an electric cooling water pump and an electric cooling fan to stop (step S100), waits for elapse of a preset reference time period since start of the control of stopping the motors (step S110), and turns off a relay to disconnect a supply of electric power from a battery to a CPU of a control unit (step S120). Inactivation of the relay after elapse of the preset reference time period since start of the control of stopping the motor disconnects the supply of electric power to the control unit in the state of sufficiently low back emf generated by the motors. This arrangement effectively prevents malfunction of the control unit due to the back emf generated by the motors.

    • A method and device for removing ice from overhead conductors of a bundle of conductors or preventing an accumulation of ice on these conductors. The method includes forcing the entire current load of the line in one or a portion of the conductors, the excessive power dissipated in this manner de-ices the conductor by Joule heating. The method is repeated for different conductors of the bundle until they have all been de-iced or for the entire duration of an ice storm. Electric power units are provided on each conductor to control the current circulation as needed, and a command module controls the entire system. Conducting elements are provided at the beginning and at the end of the line to allow a distribution of the current as needed.

    • Circuit (10) for generating an error voltage (26) which is proportional to the difference between a desired value of a physical parameter and the actual value of the physical parameter. The circuit (10) operates by alternately switching the current from a source (13) through a fixed resistor (11) and a variable resistor (12), the resistance value of which changes as a function of the physical parameter to be controlled. The current is switched between the two resistors so that the average voltage generated across the variable resistor would be equal to the average voltage generated across the fixed resistor if the physical parameter had the desired value. By determining the difference between the average voltage across the resistors, the error voltage (26) can be generated for controlling the physical parameter.
    • 用于产生与物理参数的期望值与物理参数的实际值之间的差成比例的误差电压(26)的电路(10)。 电路(10)通过交替地切换来自源极(13)的电流通过固定电阻器(11)和可变电阻器(12),其电阻值作为要控制的物理参数的函数而变化。 电流在两个电阻之间切换,使得如果物理参数具有所需值,则跨可变电阻产生的平均电压将等于固定电阻上产生的平均电压。 通过确定电阻器两端的平均电压之差,可以产生误差电压(26)以控制物理参数。
