    Abstract: A cutting insert, and more particularly, an improved double-sided cutting insert is provided, which provides improved machinability obtained due to increased rake angle, without compromising coupling state. The double-sided cutting insert includes a top surface, a bottom surface, a plurality of lateral relief surfaces connecting the top and bottom surfaces, and a cutting edge formed by the top and bottom surfaces and the plurality of lateral relief surfaces, in which one or more lateral relief surfaces of the plurality of lateral relief surfaces are formed into three stages in sequence which are a first positive surface, a negative surface and a second positive surface in a direction from the top surface to the bottom surface.

    Abstract: The present invention relates to a switch control circuit, a switch control method, and a converter using the same.An input voltage rectified from an AC input in a converter is transmitted to an inductor, and output power is generated from an inductor current by the input voltage. The converter includes a power switch connected to the inductor to control the inductor current and a sense resistor having a first end connected to a ground and a second end connected to the AC input. At a time point that a sense voltage generated in the sense voltage reaches the peak point and then decreased to an on-reference voltage, the power switch is turned on. The on-reference voltage is a sense voltage at a resonance start time point between a parasite capacitor of the power switch and the inductor.
