KB1088EP VEHICLE-BOARD NETWORK VOLTAGE REGULATOR Family of unpackaged ICs of regulator of car - system voltage of automobiles and tractors. IC of voltage regulator is meant for stabilization of voltage, which is produced by car-system generating set of automobiles and tractors, not depending on engine rotation number and load current in car system. Principle of voltage regulator action is in change of output pulse duty ratio within wide limits, affected by changes of voltage that is produced by car - system generator, from which the IC is supplied. IC output works for power composite transistor that is directly connected to excitation generator winding. With change of regulated voltage, affected by external factors, output pulse duty ratio changes and accordingly high or low power is supplied to excitation winding in order to recover broken balance. In the middle of the control range, duty ratio is approximately equal to two (Q=2) at pulse repetition frequency on IC output not less than 1000Hz.
