1、coaxial resonance circuit

2、The impedance formula of RL-C parallel resonance circuit is deduced theoretically, and some properties of resonance characteristic curve are analysed.

3、The series resonance circuit is simple, its start easy and resonance-frequency high. It is suitable in small power induction heating supply.

4、Mesoscopic double resonance circuit with complicated coupling is quantized by the method of harmonic oscillator quantization and linear transformation.

5、A new type of HAPF is expatiated including a fundamental series resonance circuit which decreases the capacity of inverters.

6、series connected ferroresonance circuit
