Abstract:
A switched-mode power supply includes a transformer, a switching element, a switching controller, a voltage generator circuit, an overvoltage protection circuit, and a load increase circuit. The overvoltage protection circuit is configured to, when a first DC voltage outputted from the voltage generator circuit is below a predetermined voltage, apply a first drive voltage to an input terminal of the switching controller, and to, when the first DC voltage exceeds the predetermined voltage, apply a second drive voltage, which is different from the first drive voltage, to the input terminal, whereby the switching controller stops controlling switching operation. The load increase circuit is configured to, when the output voltage exceeds a threshold voltage, flow a current from the secondary side, thereby increasing a load applied to the secondary side. The threshold voltage is less than a rated voltage of the transformer and greater than the target voltage.

Claim (Index 1):
A switched-mode power supply ( 1 ), comprising:\n a transformer ( 11 ) having a primary side and a secondary side, the transformer including a primary winding (L 1 ) on the primary side, a secondary winding (L 2 ) on the secondary side, and an auxiliary winding (L 3 ) on the primary side, the secondary winding being connected to a load device; a switching element ( 13 ) connected to the primary winding of the transformer; a switching controller ( 21 ) including an input terminal (VCC), the switching controller being configured to control switching operation of the switching element such that an output voltage on the secondary side of the transformer becomes a target voltage; a voltage generator circuit ( 22 ) located on the primary side of the transformer, the voltage generator circuit being configured to rectify and smooth an alternating current (AC) voltage induced to the auxiliary winding and output the rectified and smoothed AC voltage, wherein the rectified and smoothed AC voltage is a first direct current (DC) voltage; an overvoltage protection circuit ( 23 ) located on the primary side of the transformer, the overvoltage protection circuit being configured to, when the first DC voltage is below a predetermined voltage, generate a first drive voltage from the first DC voltage and apply the first drive voltage to the input terminal, the overvoltage protection circuit being configured to, when the first DC voltage exceeds the predetermined voltage, generate a second drive voltage, which is different from the first voltage, and apply the second drive voltage to the input terminal, whereby the switching controller stops controlling the switching operation; and a load increase circuit ( 30 ) located on the secondary side of the transformer, the load increase circuit being configured to, when the output voltage exceeds a threshold voltage, flow a current from the secondary side of the transformer, thereby increasing a load applied to the secondary side of the transformer, wherein the threshold voltage is less than a rated voltage of the transformer and greater than the target voltage.
