UNINTERRUPTED POWER SUPPLY APPARATUS IN ULTRASOUND SYSTEM

摘要

PURPOSE: An ultrasonic power supply device in an ultrasonic system is provided to stably supply an input voltage to an external device. CONSTITUTION: An AC/DC power converter(210) converts AC power from a power input terminal of an ultrasonic system to DC power. If the voltage of the DC power from the AC/DC power converter does not satisfy a proper voltage, a charging and discharging control circuit(240) supplies power stored at a battery(250) to the embedded computer(120) of the ultrasonic system by controlling a DC/DC power converter(220).
