Why does series resonance have similar characteristics to power sources?
2025-10-28Usually, we will find that series resonance (also known as series resonance test device) has similar related characteristics of the power supply, and the reason for its similar related characteristics is also due to its own basic circuit structure. For a current source, its characteristic is that the current value it outputs is not affected by external loads and is only related to its own factors.And for the voltage source, its output voltage is also related to its own factors, and has no relationship with other external loads. At the same time, they will not be affected by external loads or factors that cause changes in voltage and current. Simply put, as long as they do not change themselves, the values they output are constant.Usually, when we refer to a component with similar power characteristics, it means that its output power is independent of other external factors or has little relationship with other load factors. Therefore, we call it a component with similar power character

What are the sources of frequency error in series resonance?
2025-10-28Series resonance (also known as variable frequency series resonance withstand voltage device) may inevitably experience some errors during use. So, what are the main sources of frequency errors? Firstly, it is possible that there may be errors between the resistors, capacitors, inductors, and other instruments used in the experiment and their rated values. However, the errors caused by this may not be significant, usually only accounting for a few percent of the possibility, but the difference can even be around plus or minus ten percent. Such errors are considered relatively large.Then errors may occur when connecting circuits in a series resonance test circuit due to improper operation, resulting in errors such as wire resistance, welding resistance, parasitic capacitance, and parasitic inductance. However, these errors can be said to be very small, usually accounting for a few thousandths of the possible errors.Of course, when conducting experiments, it is humans who are doing the e
