Problems solved by technology

However, most approaches add complexity, size, or price to the power supply
Or, generate high-frequency switching noise in the power supply, or put stress on the power supply and cause the power supply to fail
Therefore, the reliability of the power supply unit is reduced or the life of the power supply unit is significantly reduced

Embodiment Construction

[0059] Exemplary embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0060] figure 1 is a block diagram of a power supply system 100 according to an example embodiment of the present invention. Such as figure 1 As shown, the power supply system 100 includes an AC power source 110 , a power supply device 120 and a load 140 . The AC power source 110 may be a 60 Hz power source used in residential or industrial settings. The load 140 may be an electronic or electrical device used in residential or industrial fields. For example, load 140 may be an inductively coupled plasma (ICP) device.

Abstract

The power supply includes an inverter configured to convert direct current (DC) power to alternating current (AC) power, an impedance matching circuit configured to provide the AC power to a load, and an impedance matching circuit configured to regulate the output of the AC power The arrangement of the supply period and the freewheeling period when the AC power is not output is a controller for adjusting the amount of power supplied by the inverter to the load through the impedance matching circuit.

Description

technical field [0001] The present invention relates to electronic or electrical devices, and more particularly to a power supply device and a method of supplying power to a load. Background technique [0002] Various electronic or electrical devices used in domestic or industrial places require power supply units. Electronic or electrical devices may require different types of power supply devices depending on their use, characteristics, or usage environment. In electronic or electrical devices, especially inductively coupled plasma (ICP) devices require an alternating current (AC) power supply with high power and high frequency. [0003] Controlling the amount of power or current supplied to the ICP device is required to precisely control the operation of the ICP device. Various methods have been investigated to control the amount of power current supplied to an inductively coupled plasma device. However, most approaches increase the complexity, size, or price of the po...
