Abstract

A constant frequency power supply applied in an exchange-type circuit having a primary winding and a secondary winding includes a first core, a second core, a first bobbin, and a second bobbin. The first core and the second core being disposed in opposite position have a first protruded body and a second protruded body respectively. The first bobbin being positioned on the first protruded body and having a first set of coils wound around thereof is electrically connected to a first set of connecting pins of the primary winding The second bobbin being positioned on the second protruded body and having a second set of coils wound around thereof is electrically connected to the second set of connecting pins of the secondary winding. The first bobbin further includes a slip opening that is capable of slipping on the second bobbin. A sliding telescopic combination is formed by making use of the slipping opening to perform displacement motion on the first protruded body and the second protruded body in order to perform the action of adjusting the inductance between the primary winding and the secondary winding.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to a constant frequency power supply, and more particularly, to a constant frequency power supply applied in a bridge-type circuit that is capable of replacing the inductance in the primary winding. [0003] 2. Description of the Prior Art [0004] In recent years, the high technology makes giant strides. Especially, it changes with each passing day in the field of micro-electronic relevant manufacturing process technology. Therefore, the electronic-related products having gone deep into each family and all walks of life become an indispensable portion in modern life. Certainly, the fact that the demands of human being are getting more and more makes the electronic devices become multi-functional. Consequently, the electronic devices have stepped into the target of having the multi-functional efficacy. In addition, in order to ensure that the damage or destruction of the electronic products to the ...
