The reference current output circuit (403) is used to output the reference current generated by the reference core circuit (402) in proportions.

The current supply circuit section is configured so as to supply the magnetization reversing current to the second terminals of the first and second magnetoresistive elements.

A coil of feedback to deliver the current measurement, directly proportional to the primary current and the ratio of the number of coils primary/secondaire10.

Mounting is therefore supplemented by a current generator auxiliary enslaved to the value of the voltage measured by the voltmeter, to deliver the current in the noted voltmeter IV

The bias current source is adapted to deliver a variable current.

The electric storage means can supply power to the electric motor and can be charged by regenerative power from the power-generating device.

The supply current used to deliver the pulses is therefore dependent upon the data pattern.

The third stage is configured to deliver DC power to the connected LED lamp.

Energy may be stored in a highly responsive energy storage device, such as a capacitor, for rapid delivery of power to the injector motor.

The lighting system further includes a power supply for delivering D/C current to the lighting device.

The system includes a travelling cable for delivering DC power to the car.

The reference current output circuit (403) is used to output the reference current generated by the reference core circuit (402) in proportions.

The current source is configured to output a current based on a voltage source (332).
