Abstract：In this paper, the working principle of philips color ultrasound named by EPIQ7C and the software and hardware process
of power startup were introduced in detail firstly. Then, the detection of power failure was mainly discussed in combination with the
equipment failure condition. By analyzing the voltage threshold of power module interface connection diagram and power module,
the isolation detection method of power failure was discussed. It provided strong data and theoretical support for the power modular
maintenance of EPIQ7C.
