    A NOVEL LOAD CURRENT CONTROL METHOD FOR A LEADING POWER-FACTOR VOLTAGE-SOURCE PWM RECTIFIER
    (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1994) VEAS, DR; DIXON, JW; OOI, BT
    A novel PWM voltage source rectifier, controlled by the load de current instead of the de voltage, has been developed. Its main characteristics are: a) there is neither input current sensors nor de voltage sensor; b) it works with an unchangeable and predefined PWM pattern; c) it presents a very strong stability; d) its stability does not depend on the size of the de capacitor; e) it can work at leading power factor for all load conditions, and f) it can also work with zero regulation for all load conditions. Digital simulations, analyses, and experiments confirm all these characteristics of the control method.
