摘要： Disclosed is a variable inductance applying device using a variable capacitor, and a variable frequency generating device thereof. The variable inductance applying device includes: a first inductor whose both terminals are connected to an inductance applying terminal applying inductance to an external circuit; a second inductor inductively coupled to the first inductor; and a variable capacitor connected to both terminals of the second inductor, which varies inductance from the inductance applying terminal by changing capacitance. Therefore, the inductance to be applied to the external circuit can be varied by changing the capacitance of the variable capacitor. Since the variable capacitor rarely contains a resistance component, energy loss due to the resistance component hardly occurs. As a result, the variable inductance applying device has a high value of Q.
