This invention provides an integrated magnetically controlled
transformer system and its method for stabilizing output
voltage. The
system includes a main
transformer, an auxiliary
transformer, an AC / AC converter, and a controller. The input of the main transformer is connected to a high-
voltage power grid, and its output provides a main
voltage containing disturbance components. The primary side of the auxiliary transformer is connected to the output of the AC / AC converter, and its
secondary side is connected in series to the output circuit of the main transformer. The input of the AC / AC converter is connected to the output side of the main transformer. The controller samples the output voltage of the main transformer in real time and compares it with a set voltage value to generate a command
signal for controlling the AC / AC converter. This allows the adjustable compensation voltage to cancel out the disturbance components in the main voltage in real time, thereby stabilizing the total output voltage after series superposition at the set voltage value. This
system effectively isolates voltage disturbances on the
power grid side, ensures
voltage stability on the load side, has a fast response speed,
high voltage regulation accuracy, and a compact and reliable structure.
