Wuhan UHV specializes in producing series resonance (also known as series resonance test device). Next, we will share with you how series resonance resonates and its principle analysis.

In an AC circuit with resistor R, inductor L, and capacitor C, the voltage at both ends of the circuit is generally different in phase from the current in a series resonant circuit. If we adjust the parameters of circuit components (L or C) or power frequency, they can be in the same phase, and the entire circuit exhibits pure resistance. The ability of a circuit to achieve this mental state is called resonance. The maximum or near maximum total impedance of a circuit in a resonant state. The main purpose of studying resonance is to recognize this social objective phenomenon and fully develop and utilize its characteristics in Chinese science and applied technology, while also preventing the harm it may cause. According to the circuit connection, there are two types: series resonance and parallel resonance

When the series resonant reactive power, the capacitor voltage and inductor voltage are equal in magnitude and opposite in direction, that is, the LC absorption is equal but opposite in direction, resulting in zero reactive power absorption by the circuit; The constant changes in electrical and magnetic energy, but this increase reduces and compensates for the energy oscillating between the electric and magnetic fields, the sum of the electromagnetic energy of the entire circuit constant, and a portion of each other; The excitation energy supply circuit becomes a complete resistance heating. In order to maintain oscillation, we must continuously increase the supply energy to compensate for the heating consumption of the resistor. Compared with the total electromagnetic field energy management in the circuit, the less energy is consumed per oscillation, and the better the quality of the circuit.

The principle of series resonance and series resonance circuit

With the continuous growth of high-capacity testing programs established in power systems such as cables and power systems, the exchange applications of various parts of series resonant power supplies are becoming more and more widespread. It requires us to recognize that deep series resonance, we will discuss the principles of series resonance and series resonant power supplies together on site, and discuss the application programs and everyone.

The principle of series resonance

Firstly, let's talk about the generation of resonance. Resonance is a special educational phenomenon that occurs in circuits composed of important R, L, and C components under certain economic conditions. Let's lead everyone in China to analyze the conditions under which resonance occurs in the circuit structure of the R, L, and C series system and the characteristics of the circuit during resonance.
