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.

Abstract: An apparatus for preventing withdrawing and insertion of a carriage of a circuit breaker is disclosed. When a circuit breaker main body is inserted, an interlocking unit operates by interworking with the carriage withdrawing and inserting preventing apparatus, and while the circuit breaker is being closed, a withdrawal and insertion handle prevents a lead screw from being rotated by the interlocking unit. Thus, when the circuit breaker performs a closing operation, unnecessary withdrawing and inserting operation of the carriage is basically prevented to thus prevent various safety accidents, a contact resistance, a temperature increase, and damage to a device resulting from a breakdown.
