Digital voltage regulator includes digital single-phase voltage regulator and digital three-phase voltage regulator, as an AC voltage regulator, it adopts an integrated design combining digital three-phase power controller and load-matching transformer and it realizes the continuous regulation of output AC power by the way of phase shift & voltage regulation at the primary side of the load-matching transformer. It has open-loop or various closed-loop control forms and multiple given control signal selections.
Digital voltage regulator realizes the matching of load power and voltage by changing the power and transformation ratio of the load-matching transformer according to the requirements of actual load power and voltage and it can be widely used in the continuous regulation and control of single-phase or three-phase AC power of automatic temperature control systems such as various industrial heating and heat treatment system etc.
