A New Type of Energy-Saving Magnetic Amplifier Controlling Inductive Load

Article Preview

Abstract:

A new type of energy-saving magnetic amplifier controlling current and voltage of inductive load has been designed. The energy-saving magnetic amplifier with two windings wrapped across one iron core column can change impedance of the main winding by means of PWM controlling AC excitation current. The energy-saving magnetic amplifier has not used a special adjustable DC voltage circuit, has overcome disadvantages of complicated manufacturing process for the traditional excitation amplifier.The application shows the energy-saving excitation amplifier can achieve stepless dimming for high pressure sodium lamp to good energy-saving effect. The use cost of excitation amplifier is lower as simple production process, so its promotional value is great.
