摘要

ELECTRONIC VOLTAGE REGULATOR. A TRADITIONAL CIRCUIT FORMED BY A TRIAC CONTROLLED BY A DIAC IS ADDED A CIRCUIT TO REGULATE ITS TIME CONSTANT. THIS IS ACHIEVED BY THE VARIATION IN THE OHMIC VALUE OF A PHOTORRESISTIVE CELL (CF). THIS, PLACED IN A DARK CHAMBER, RECEIVES MORE OR LESS LIGHT FROM A LAMP (LD) ACCORDING TO THE POSITION OF THE DIAPHRAGM (P), WHICH SEPARATES THEM, AND WHOSE VARIABLE SECTION OPENING, MOVES WITH THE PLATE, FOLLOWING THE MOVEMENT OF A PEDAL OR ROTARY CONTROL. OF APPLICATION IN THE SPEED REGULATION OF SMALL ELECTRIC MOTORS. (Machine-translation by Google Translate, not legally binding)
