Title: Single-Phase Photovoltaic Power Conditioning System and it's Notch filter Design Method
Inventor: KIM YONG REA
IPC: H02S40/32
Filed: 2019-03-25
Abstract: The present invention relates to a single-phase photovoltaic device and a method for designing a notch filter for the single-phase photovoltaic device. More specifically, when the single-phase photovoltaic device is connected to a system and operated in a system connected mode, an AC ripple of a low frequency of 120 Hz, which is twice the frequency of the system, is generated at an output DC-Link terminal of a DC/DC converter by the system. The 120 Hz low-frequency AC ripple shortens the lifespan of a capacitor and increases the total harmonic distortion (THD) of the output current of the single-phase photovoltaic device. As a result, since the efficiency of the single-phase photovoltaic device is lowered, the notch filter is used to remove the AC ripple component of the low frequency of 120 Hz caused by the system, and the efficiency is increased. In addition, when designing a digital notch filter, the THD decreases as the switching frequency increases, and the size of an LC filter decreases, which is significantly affected by the switching frequency (the reciprocal of the sampling frequency). Therefore, a cost-function for determining an optimal switching frequency is presented, so that an optimal design method in consideration of the overall performance of the photovoltaic device is achieved.

Title: Interior-type floating pattern pillow with customized bearing capacity
Inventor: YEO JEONG HYEON
IPC: A47G9/10
Filed: 2019-04-25
Abstract: The present invention relates to a pillow with an internal material moving pattern for providing customized support force which adjusts the content of a filling material in a pillow to allow the pillow to naturally move to match the body structure of a user by the principle of the lever and automatically adjust the pressure applied to the back of the head, the cervical spine, and the temporal region. To this end, the content of a filling material of a back head support unit and a neck bone portion support unit for placing and supporting the neck bone thereon when a user is lying in a proper position is adjusted to relatively reduce the amount of the filling material of the back head support unit. When the back of the head of the user presses the back head support unit, the height of the back support unit is lowered and a rising pressure is applied to the neck bone portion support unit. Specifically, the distance between a support point and an action point can be adjusted by adjusting the width of the neck bone portion support unit and the back head support unit. Accordingly, the rising pressure of the neck bone portion support unit in comparison to the pressure applied by the back of the head can be adjusted. Also, the rising pressure is created by an open pattern, and the internal material moves between the back head support unit and the neck bone portion support unit in accordance with the pressure. Therefore, the more the pillow is used, the better the pillow matches the angle of the cervical spine and the back of the head of the user.

Abstract: The present invention relates to a frequency mixing unit operated as a double-balanced mixer when a DC voltage is applied to a part of switch elements or the phase of a local oscillation signal input to the switch element is changed while a single frequency mixing unit formed of switch elements basically operates as a sub-harmonic mixer. According to the present invention, since a frequency mixer which uses a fixed LO frequency and selectively performing operation of a sub-harmonic mixer performing 2*LO frequency conversion and a dual-balance mixer performing LO frequency conversion based on the same hardware is introduced, a settling time of PLL (Phase-Locked Loop) is omitted to provide a fast spectrum analysis time, and the number of frequency channel paths is reduced to reduce complexity of the receiver. Moreover, an RF feedthrough problem, which is generated odd harmonics of LO frequencies in a two-stage frequency mixer selectively supporting a sub-harmonic mixer and a double-balanced mixer, can be solved through a sub-harmonic frequency mixer configured in a single-stage parallel form. The frequency mixer comprises a first switching end and a second switching end.
