Intelligent transformer and control method thereof

The invention discloses an intelligent transformer and a control method thereof. According to the intelligent transformer and the control method thereof, the current direction of the primary coil is automatically adjusted or the primary coil current is turned off according to the input voltage; the output voltage is directly output by coupling superposition or reduction of a certain proportion ofvoltage on the basis of the mains supply or without transformer coupling, so that the mains supply with a large fluctuation range is stabilized within a rated voltage range, and the intelligent transformer and the control method have the advantages of large control range, low power consumption, low control cost and the like. 本发明公开了一种智能变压器及其控制方法，该智能变压器及其控制方法根据输入电压自动调整初级线圈的电流方向或关断初级线圈电流，输出电压在市电的基础上通过耦合叠加或降低一定比例的电压，或不通过变压器耦合直接输出，使波动范围较大的市电稳定在额定电压范围内，具有控制范围大，功耗小，控制成本低等优点。
