Latest Patents
Nicol's latest patents include innovative designs for battery charging systems for road vehicles. One of his patents describes a battery charging system that features an alternator with a rectifier connecting the alternator output to the battery. This system utilizes a voltage rectifier to control the current in the alternator field winding based on the battery voltage. A transistor switch in the voltage regulator manages the bias current to the output stage of the regulator, which is controlled by a differential amplifier through a diode pump. The differential amplifier detects the presence of an alternating current on one phase of the alternator, switching off the transistor and disabling the output stage of the regulator when no a.c. signal is present.
Another patent focuses on an automotive battery charging system that incorporates a novel temperature compensation arrangement. This system includes a conventional input potential divider with an additional resistor and a temperature compensation output transistor in series across one leg of the divider. The voltage at the base of the temperature compensation output transistor is regulated by a temperature sensing circuit, ensuring it decreases linearly with rising temperature. Resistors are adjusted during manufacturing to achieve the desired level and slope for the temperature compensation characteristic.
