Embodiment Construction

[0018] Preferred embodiments of the present invention are described with reference to the accompanying drawings. Hereinafter, the same reference numerals correspond to the same elements in each embodiment.

[0019] Figure 1A and 1B They are respectively a front view and a rear view of a contactless power supply according to the present invention. figure 2 It is a schematic circuit diagram of the non-contact power supply according to the present invention.

[0020] Such as Figure 1A to Figure 2 As shown, the non-contact power supply according to the present invention has the characteristics of long service life and no malfunction. Here, when the load-side power supply control system is designed in various schemes, the contactless power supply can be adapted to various situations.

[0021] For example, refer to Figure 1A and 1B , the non-contact power supply according to the present invention applies power to the rotation unit (not shown) of the motor (M) to operate the...

Abstract

A contactless power supply is provided, which includes a main body; a primary circuit having a power input portion receiving main power, a switching circuit having a plurality of direct-current (DC) converter, and a primary transformer, which is disposed in one-side of the main body; and a secondary circuit having a secondary transformer which is disposed at a predetermined distance from the primary circuit and receiving power from the primary transformer contactlessly, a peripheral circuit which filters and rectifies the power, and a power supply unit supplying the rectified power to a control system. As described above, the contactless power supply has a long life span of use and a characteristic of non-occurrence of mis-operations as well as an efficient power transfer function even at the state of a low coupling coefficient and a large leakage inductance, due to a contactless power transfer, in which a load-side power supply control system is designed in various schemes so as to be adapted in various ways.

Description

technical field [0001] The present invention relates to a non-contact power supply, in particular to a non-contact power supply with long service life and no malfunction. It still has the function of high-efficiency power transmission in the state of inductance. Among them, the load-side power supply control system is designed with various schemes to adapt to various situations. Background technique [0002] Most conventional electric motors, braking systems or battery charging systems use contact power with conventional contact circuits. [0003] Contact power supplies have the advantage of being relatively simple and low cost, but have a limited lifespan. Meanwhile, the application of the contact power supply has gradually decreased since it has such a disadvantage that all circuits need to be redesigned when the control environment changes. [0004] In addition, due to the impressive development of semiconductor technology today, non-contact power supplies with non-cont...
