STEP-BY-STEP AC VOLTAGE REGULATION DEVICE Russian patent published in 2005 - IPC

FIELD: electrical engineering; fast-response and high-precision ac voltage regulators.

SUBSTANCE: proposed ac voltage regulation device has input and output leads; common point; first transformer that has main winding connected between input lead and common point of device and sectionalized winding whose taps are connected to respective inputs of controlled switch; second transformer whose secondary winding is connected between input and output leads of device; controlled phase shifter interconnecting second transformer primary winding, controlled switch output, and common point; first transformer functions to step up voltage by minimum two times of its regulation range and second transformer is used to accordingly step down this voltage.

EFFECT: reduced value of handled currents.
