Abstract: A method and apparatus for controlling a converter of a fuel cell vehicle that uses a power control value generated based on an inverter DC terminal voltage as a reference value, and generates a current reference signal based on the reference value is provided. More specifically, the method and apparatus output a final reference signal that generates a pulse width modulation (PWM) signal by compensating for the current reference signal based on output terminal current of the converter. A peak value is then increased by amplifying a triangular wave signal, and the amplified triangular wave signal and the compensated final reference signal according to the current reference signal change rate are compared. A PWM signal having a predetermined duty ratio is then generated to control the converter.

Abstract: A mobile communication terminal and operating method thereof. The terminal includes a housing configured such that one portion of the housing can rotate against the other portion of the housing. A joint mutually joins an upper housing with a lower housing of the mobile communication terminal and enables one of the upper and lower housings to be obliquely twisted to rotate against the other. After providing an input signal to the mobile communication terminal having thus joined, twisting to rotate either the upper or lower housing against either the lower or upper housing in one direction obliquely orients a microphone near a user's mouth. Twisting the upper and/or lower housing also sends the input signal to a base station automatically.
