Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0015] like figure 2 As shown, a method for uninterrupted power supply of an intelligent computer power supply comprises the following steps:
[0016] (1) Connect the mains power to the computer, and the computer is in normal operation, so that the mains power is transformed into a 12V DC voltage by the high and low voltage conversion filter circuit, of which one 12V DC voltage is used for computer power, and the other 12V DC voltage is converted by DC / DC Circuit 5 converts other groups of DC voltages required by the computer;
[0017] (2) Whether the power-off signal monitoring circuit monitors whether the power supply signal is suddenly disconnected, if so, enter the next step, otherwise, the computer operates normally;
[0018] (3) Start the battery switching circuit to directly switch the 12V storage battery for use to output 12V DC volt...
