Abstract
Abstract CURRENT VARIATION IS SENSED AS A VOLTAGE CHANGE ACROSS A SENSING RESISTOR CONNECTED IN SERIES BETWEEN A SERIES PASS TRANSISTOR AND A LOAD TERMINAL. THE VOLTAGE CHANGE COUPLED TO ERROR SENSING MEANS WHICH COUPLES A CONTROL VOLTAGE TO THE PASS TRANSISTOR TO CONTROL THE LOAD CURRENT. A COMMON TERMINAL OF A FLOATING VOLTAGE SUPPLY IS COUPLED TO ONE SIDE OF THE SENSING RESISTOR SUCH THAT A REFERENCE VOLTAGE COUPLED TO THE ERROR SENSING MEANS IS CONSTANT WITH RESPECT TO THE COMMON TERMINAL VOLTAGE AND DOES NOT VARY WITH THE LOAD CURRENT.
