1. Basic principles of transformer modelingThe actual modeling of isolated power transformers is more complicated. Not only the parasitic parameters between different windings, but also the windings and cores must be considered. parasitic capacitance between. In the high-frequency band, physical-lev

First, let’s talk about what crosstalk is. Crosstalk is two traces on a PCB. When they are not in contact with each other, one side interferes with the other, or interferes with each other.The main manifestation is that the waveform has abnormal clutter, which affects signal integrity (SI) and so o

As can be seen from the above figure, the switching power supply is in the process of turning on and off the MOS tube. , the voltage of the primary side of the transformer and the part of the wire connecting the primary side of the transformer to the drain of the MOS tube is changing rapidly. This l

In an asynchronous machine, the transfer of energy depends on magnetic flux. This is considered from the perspective of energy conversion. To drag the load, sufficient mechanical energy is required, and this mechanical energy must be obtained from electrical energy. , and the link of transmission is

The application of motor forward and reverse is very extensive, and it is also one of the required items for the low-voltage electrician practical examination. Only when we fully understand its working principle and action process can we flexibly use it in practical work. And when a fault occurs, we

Modern power conversion equipment typically uses switching technology, which requires special handling for measurements, including the use of differential probes. This is because, unlike previous analog devices, these devices do not use a transformer to step down the line voltage, but instead use th
