  • Damage Limitation
    Publication number: 20140293665
    Abstract: A damage limitation approach comprising determining that a voltage produced by a rectifier circuit is indicative of a fault and consequently controlling a switch operable to bypass a resistive element of a circuit via which the rectifier circuit is supplied.

  • Overvoltage Protection
    Publication number: 20140153140
    Abstract: A power supply arranged to charge a smoothing capacitance via a resistive element for soft-starting in the event that one or more conditions for normal operation are not complied with is arranged to detect that a voltage across at least part of the smoothing capacitance exceeds an excess voltage threshold and, responsive to the detecting, interrupt charging of the smoothing capacitance via the resistive element for soft-starting.

  • Circuit For Monitoring The Operation Of An Electric Motor
    Publication number: 20140125262
    Abstract: A circuit for monitoring the operation of an electric motor comprises means for deriving a motor signal indicative of a relatively low frequency characteristic of the motor commutation current (for example the back EMF ripple) by rejecting the high frequency components which are mainly the result of the commutation events. The circuit also includes means for producing a pulse from the low frequency characteristic which has a duration related to the motor speed.
