Abstract:
A power supply circuit which can suppress current surges comprises a first switch unit, a first control unit, a second switch unit, and a second control unit. The first switch unit is coupled between a voltage input terminal and a load, the load comprising a capacitor. The second switch unit is coupled between the voltage input terminal and the load. The second control unit turns on the second switch unit to charge the capacitor to a predetermined voltage before the first control unit controls the first switch unit to turn on. The second control unit controls the second switch unit to turn off when a voltage of the capacitor is greater than the predetermined voltage, and the first control unit controls the first switch unit to then turn on to supply power to the load.

Claim (Index 8):
A power supply circuit comprising:\n a first switch unit coupled between a voltage input terminal and a load, and the load comprising a capacitor; a first control unit coupled to the first switch unit and configured to control the first switch unit to turn on or off; a second switch unit coupled between the voltage input terminal and the load; and a second control unit coupled to the second switch unit, and configured to control the second switch unit to turn on to charge the capacitor to a predetermined voltage before the first control unit controls the first switch unit to turn on; and wherein when a voltage of the capacitor is greater than the predetermined voltage, the second control unit controls the second switch unit to turn off and the first control unit controls the first switch unit to turn on to supply power to the load; wherein the second control unit comprises: a comparator, a positive input terminal of the comparator coupled to the capacitor; and an adjustable stabilivolt, an anode of the adjustable stabilivolt grounded, and a cathode of the adjustable stabilivolt coupled to a negative input terminal of the comparator; and wherein the second switch unit comprises: a first transistor, a control terminal of the first transistor coupled to an output terminal of the comparator, and a first terminal of the first transistor coupled to the voltage input terminal; a first resistor coupled between the control terminal of the first transistor and a second terminal of the first transistor; and a second transistor, a control terminal of the second transistor coupled to the control terminal of the first transistor, a first terminal of the second transistor coupled to the capacitor, and a second terminal of the second transistor coupled to the second terminal of the first transistor.
