Broadband High Power Switch {SWITCH FOR BROADBAND AND HIGH POWER}

The present invention relates to a switch for high power, and relates to a broadband high power switch using an electromagnet.

Many mobile devices and home appliances rely on batteries, but they are limited in time after charging, and most of them restrict users' movement by supplying power by power cords or electric wires. Because of these limitations, continuous mobile service is difficult to solve without the power problem, and it is impossible to establish a true network environment.

In order to solve this problem, many technologies are being developed to transfer energy wirelessly. For example, a radio wave reception type technology using a microwave, a magnetic induction type technology, a magnetic resonance technology by energy conversion of a magnetic field and an electric field are typical.

At this time, these technologies are forced to increase the size of the hardware such as the antenna portion of the system to directly transmit the low frequency (60Hz) power of the outlet, which is sufficient efficiency when reduced to the size for use in real life Since it cannot be obtained, it is actually converted to energy to wirelessly transmit tens to hundreds of watts of power.

In the related art, it is possible to adjust manually with one variable element, but since it usually needs to be controlled automatically by a digital control signal, it is composed of a plurality of switches, a plurality of inductors and capacitors, and a bank (inductor bank, capacitor bank). Inductance and capacitance values are adjusted by opening and closing the switch using a digital control signal.

In addition, most switches are electrical switches based on semiconductor properties such as transistors (FETs) or pin diodes. They are capable of switching over frequencies up to several tens of GHz, but have high losses, making switching difficult for powers of several tens of watts or more, and driving at very high voltages.
