Accompanying drawing 1 is an AC/DC server power supply principle schematic.
Description of reference numerals, FU1 and FU2 are fuse, can play the effect of input overcurrent protection; B is the power frequency step-down transformer, and the 220V alternating current is reduced to low-voltage AC; Q is a rectifier bridge, and alternating current is converted to direct current; IC1 is an integrated regulator, and output is designed to be higher than the voltage of 48V; D1 and D2 are rectifier diode; C is for keeping electric capacity, and switching moment at AC and DC is the IC2 power supply; IC2 is the DC-DC switch power converter.
Embodiment
With reference to Figure of description to explaining below the work of the present utility model.
AC/DC server power supply of the present utility model, its structure are by with reference to the accompanying drawings, and content of the present utility model is illustrated its principle with instantiation.
Operation principle is as follows:
When having only the 220V Alternating Current Power Supply, 220V exchanges and reduces to low-voltage AC through B, be direct current through the Q rectification again, IC1 is (through the hypotensive effect of B, integrated regulator IC1 is the low-voltage input, reduced the design difficulty of integrated regulator IC1) be responsible for this direct current is carried out voltage stabilizing, require integrated regulator IC1 output dc voltage to be higher than 48V. this moment, the conducting of diode D1 positively biased, the anti-Pianguan County of diode D2 is disconnected, integrated regulator IC1 output voltage is delivered to switch power converter IC2 through diode D1 and capacitor C, is converted to the various voltages that power consumption equipment needs through switch power converter IC2, is the power consumption equipment power supply.
When having only 48V storage battery E direct current supply, the anti-Pianguan County of diode D1 is disconnected, the conducting of diode D2 positively biased, and the 48V direct current directly is delivered to switch power converter IC2 through diode D2 and capacitor C, be converted to the various voltages that power consumption equipment needs through switch power converter IC2, be the power consumption equipment power supply.
When 220V exchanges and the 48V direct current is powered simultaneously, because integrated regulator IC1 output dc voltage is higher than 48V, the conducting of diode D1 positively biased, the anti-Pianguan County of diode D2 is disconnected, preferential selection 220V interchange provides electric power for switch power converter IC2, be converted to the various voltages that power consumption equipment needs through switch power converter IC2, be the power consumption equipment power supply.When the 220V interchange is broken down, integrated regulator IC1 output voltage disappears, the anti-Pianguan County of diode D1 is disconnected, the conducting of diode D2 positively biased, provide electric power by the 48V direct current for switch power converter IC2, be converted to the various voltages that power consumption equipment needs through switch power converter IC2, be the power consumption equipment power supply.C is for keeping electric capacity, and switching moment at diode D1 and D2 provides electric power for switch power converter IC2, so just can guarantee whole process uninterrupted power supply.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
