Abstract: The present invention relates to a method for operating an urban train. In a current train operating method, a current urban train has problems of delay in arrival time at a destination and an overcrowding train during rush hours since a train is stopped at all stations from a depart station to the last station in full. In order to solve the problems, according to the present invention, all stations are divided by zone and an exclusive train is operated at each station in a zone. A train travels the entire line in which two of six stations are stopped and four of six stations are not stopped. According to an express train operating method, an arrival time to a destination of a train is shortened, and five trains are divided by a destination to significantly relieve an overcrowded train during rush hours, such that four-fifths of the number of connecting operation trains are reduced.

Abstract: The present invention relates to control of an induction heating device which uses a voltage resonance method using a commercial AC power source. According to the fundamental principle of the induction heating device, since a high-frequency AC suitable for a material of a cooking vessel has to flow through a working coil to induce eddy current in the cooking vessel, a structure in which a DC power generated by rectifying the commercial power supplied to the working coil is switched to a power control semiconductor device at high speed is provided. When the induction heating device starts a switching operation by a pulse wave modulation (PWM) output of a micro control unit (MCU) in a standby mode in which a switching element is turned off while the DC power generated by rectifying the commercial power is supplied to the working coil, an initial high DC voltage is suddenly applied, noise is generated by a high current flowing in a working coil resonator and a semiconductor switching element, and the switching element can be burnt due to overshoot of a resonant voltage induced in the working coil resonator. To prevent generation of annoying noise and destruction of the switching element due to the initial excessive resonance voltage, the present invention provides a soft start control method of initial operation to safely move the induction heating device in a standby state to normal operation.
