Patent Number: 7,535,119

Title: Power control apparatus of a complex terminal

Abstract: A power control apparatus of a complex terminal is disclosed that includes a DC/DC converter for outputting an auxiliary power supplied from an auxiliary battery after adjusting a level of voltage of the auxiliary power to a required input voltage level of the complex terminal; a second voltage sensor for measuring voltage of a main power outputted from a main battery, and controlling the auxiliary power of the auxiliary battery to be inputted to the DC/DC converter before the measured voltage of the main power becomes lower than a predetermined voltage; and a first voltage sensor for interrupting supply of the main power from the main battery to the complex terminal and controlling the auxiliary power outputted from the DC/DC converter to be supplied to the complex terminal, when the measured voltage of the main power becomes lower than the predetermined voltage.
