AC regulated power supply is one of the relatively rare types of experimental machines for deep rail longitudinal tension and compression. To understand the performance characteristics of AC regulated power supply, here is a brief description of the main technical indicators of AC regulated power supply. Source voltage range: that is, the input voltage range. The AC regulated power supply can not stabilize the output voltage under any AC voltage input, but has an adaptive range. Source voltage effect (also known as voltage regulation rate): it is defined as "the effect of output change caused only by the change of input voltage". Su= (umax/uon) * 100% where: Umax - the * * * value (V) of the output voltage change when the input voltage is adjusted up or down. High performance programmable AC power supply adopts advanced digital signal processing technology, with power as high as 54kva and frequency as high as 5KHz. Some single-phase or three-phase products can easily rise to ac600v (three-phase star connection offline voltage * * * can reach 1000V) output by selecting boost module. Built in omni-directional power meter and large screen oscilloscope function

as shown in the figure, wind two groups of coils with opposite directions on the same magnetic ring. According to the rule of the right-hand spiral tube, when a differential mode voltage with opposite polarity and the same signal amplitude is applied to both ends of the input a and B, there is a current I2 shown by the solid line, and the magnetic flux shown by the solid line is generated in the magnetic core φ 2. As long as the two windings are completely symmetrical, the magnetic flux in two different directions in the magnetic core counteracts each other. The total magnetic flux is zero, and the coil inductance is almost zero, which has no impedance effect on the normal mode signal. If a common mode signal with the same polarity and equal amplitude is added to both ends of input a and B, the current I1 shown by the dotted line will generate the magnetic flux shown by the dotted line in the magnetic core φ 1. The magnetic flux in the magnetic core has the same direction and strengthens each other, so that the inductance value of each coil is twice that when it exists alone, and XL= ω l. Therefore, this one winding coil has a strong inhibitory effect on common mode interference. The actual EMI filter is composed of L and C. in the design, the differential mode is often combined with a total of 5. The stretching speed range: 0 ~ 500mm/min (special requirements are set separately) mode suppression circuit (as shown in Figure 2)

The AC power supply used in the experiment adopts linear amplifier mode and can control the waveform in a wide range. It is suggested that it should be used to guide and regulate the orderly development of China's experimental machine industry, and the power supply stabilization of precision machining machinery and measuring devices whose voltage will bring adverse effects. On the basis of high-speed response characteristics, the output voltage and frequency can be converted at any time. The noise of PWM frequency converter will not occur. Therefore, it can simulate the abnormal power supply of research and development, manufacturing and inspection production line in a high-precision and simple way

since entering the 21st century, switching power supply is developing in the direction of intelligence and digitization. The new AC power supply with its excellent characteristics and complete monitoring function is attracting widespread attention. AC power supply provides intelligent adaptability and flexibility, with direct monitoring, remote fault diagnosis, fault handling and other power management functions, which can meet complex power requirements. At present, there are many definitions of AC power supply. ● define the switching power supply controlled by digital interface (it emphasizes the "communication" function of AC power supply). ● define the switching power supply with digital control function (it emphasizes the "numerical control" function of AC power supply). ● define the switching power supply with digital monitoring function (it emphasizes the "monitoring" function of AC power supply for temperature and other parameters). The common feature of the above three definitions is "analog switching power supply → transformation and upgrading", which emphasizes "power control". The definition takes digital signal processor (DSP) or microcontroller (MCU) as the core
