MONOCHIP CAR ALTERNATOR REGULATOR
Description
Alternator regulator 14IVR-XX, made under the integrated technology is essentially
a monochip voltage regulator for the car alternators with the rectifier nodes on the Zener
diodes. The single chip combines the control functions and the powerful output cascade
with IField=5 A to control the generator excitation circuit. The alternator regulator 14 IVR-XX
does not require application of other external components, which considerably reduces the
system cost as a whole and enhances its reliability.

Operation of Device
Principle of operation of the voltage regulator is essentially in the porosity alteration
of the output pulses under influence of the voltage fluctuations, generated by the car
alternator, from which the microcircuit is voltage supplied.
Voltage regulator incorporates the powerful output transistor stage, ensuring the
direct connection of the microcircuit output to the excitation winding of the alternator.
Voltage, generated by the alternator, is rectified on the external diodes and
compared with the internal reference voltage of the voltage regulator. In dependence on
the value of difference a signal is generated with the width-pulse modulation, which forms
current in the alternator excitation circuit.
Application of the width-pulse modulation makes it possible to make the switching
frequency in the regulator constant and, consequently, to exclude influence of the different
kind of interferences, in particular, of the pulsations of the rectified voltage on its operation.
During voltage reduction under the influence of the external factors, generated by
the alternator, the porosity of the Q output current pulses is reduced, which results in the
current increase in the alternator excitation circuit for restoration of the upset balance.
At the rise of voltage, generated by the alternator, porosity of the Q current pulses
at the microcircuit output increases, appropriately, the current is reduced, which is applied
to the alternator excitation winding.
