Abstract
The utility model relates to a current regulating alternating current power supply with controllable amplitude modulation mainly used for requiring an output end to output a high power alternating current power supply only changing voltage amplitude without changing voltage waveform. The utility model combines laminations and coils into an iron core transformer of triple-post type and changes the magnetic flow value in three main iron cores by making use of the directional magnetization philosophy in different degrees of direct current magnetic to the alternating current magnetic in the same iron core in order to change the voltage value on a working winding to obtain the purposes of current regulating and voltage regulation. The utility model can be used as a stepless current regulating electric welding power supply and a stepless alternating current high voltage regulated power supply of amplitude modulation type.
Description
The utility model relates to a kind of controllable amplitude modulation type and transfers the stream AC power, and it is mainly used in the high-power ac power that requires a kind of of output terminal output to change voltage amplitude and do not change voltage waveform.Be specially adapted to the adjustable voltage stabilizing AC power of stepless flow-regulating type welder power and amplitude modulation.
The stepless accent stream of normally a kind of moving-iron type of the prior art power supply that is used for welder power, its core structure is a three pillar type, wherein a post is movable adjustable, it is to utilize the position of movable core in three iron core column to change the sendout of magnetic flux in the whole iron core column, realizes the adjusting of secondary current size.Its weak point is that when big electric current passed through coil, the high-intensity magnetic field of generation can make iron core produce vibrations and noise, and complex structure, regulates inconvenience owing to adopt moving-iron type.
The prior art of AC voltage-stabilizing regulated power supply is to adopt output terminal to be connected to the AC voltage adjusting method of magnetic saturation type reactor, it is to utilize an adjustable reactor and a quantitative out-put supply to be combined into a cover regulator, its weak point is when zero load or underloading, output voltage increases, so need dispose corresponding pressure regulator for certain load, its range of application is restricted.
The purpose of this utility model is for overcoming above-mentioned deficiency of the prior art, and provide a kind of and have stepless accent stream and amplitude modulation AC voltage-stabilizing adjustable function, simple in structure, easy to adjust, noiselessness, controllable amplitude modulation type that heavily loaded efficient is high is transferred the stream AC power.
The utility model is achieved through the following technical solutions, promptly make a three pillar type appendiron core transformer of forming by saturated column, work post and pressure regulation post with magnetic links and winding, utilization in same iron core column direct current flux to exchange flux with in various degree dc magnetization principle, change the AC magnetism flux size in three main iron core posts, and then the voltage distribution value on the change work winding, reach the purpose of transferring stream and pressure regulation.
Embodiment of the present utility model can describe in detail by accompanying drawing:
Accompanying drawing is lamination of the present utility model and winding connection schematic diagram;
The utility model is made one by saturated column 1 by common magnetic links and winding, work post 2, pressure regulation post 3, control winding 5, input winding 6, control winding 7, control winding 8, output winding 9, the three pillar type appendiron core transformer that output winding 10 is formed, on saturated column 1, two window formula iron cores 4 are arranged, a window formula iron core 4 is arranged on pressure regulation post 3, control winding 5 and control winding 7 are respectively on two window formula iron cores 4 on the saturated column 1, the input winding 6 respectively around saturated column 1 stage casing and work post 2, each part on the pressure regulation post 3, output winding 9 is on work post 2, with input winding 6 tight coupling on this post, output winding 10 is on pressure regulation post 3, with input winding 6 tight coupling on this post, on the window formula iron core 4 of control winding 8 on the pressure regulation post 3.
The course of work of the present utility model and principle of work are, when control winding 5,7 is zero current or open circuit, the output of control power supply connects control winding 8, regulate the input current size in the control winding 8, the direct current flux magnetization that exchange flux Be Controlled winding 8 in the pressure regulation post 3 is produced, exchange flux in this post is reduced, changing the voltage in the input winding 6 in this post, thereby reach the purpose of unloaded pressure regulation; When control winding 8 is zero current or open circuit, the output of control power supply connects control winding 5 and 7, regulates the input current size in the control winding 5 and 7, can change the exchange flux in the saturated column 1, to change the voltage of input winding 6 on this post, reach the purpose of heavy duty downward modulation stream or pressure regulation.When the utility model only is used for transferring stream electric welding source, can save control winding 8 and window formula iron core 4 parts in the pressure regulation post 3, build up the form the same with the post 2 of working.
Compared with the prior art, the utlity model has following advantage, when as welding power supply, but its output current step-less adjustment, during in particular as little electric current AC arc welding source, it is big that it has a striking current, and after the starting the arc, normal arc-welding electric current is got back to again rated value, make like this utility model can be widely used in the welder power that welds the thin type weldment, and easy to adjust, noiselessness during work, heavy duty efficient height, simple in structure; When as amplitude modulation voltage stabilizing regulated power supply, its output waveform distortion is little, output voltage stabilization.
