Abstract
A novel pulse-width-modulated (PWM) voltage source rectifier, controlled by the load DC current instead of the DC voltage, has been developed. Its main characteristics are: (a) there are neither input current sensors nor DC voltage sensors; (b) it works with an unchangeable and predefined PWM pattern; (c) it has very strong stability; (d) its stability does not depend on the size of the DC 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.ETX
