Title: Power supply
Inventor: HORIE TAKASHI
IPC: H02M3/28
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To reduce power loss in the practical application mode by providing a conversion ratio control means, which can control the conversion, ratio between input voltage and conversion voltage of a converting means depending on an amplitude of the input voltage. SOLUTION: A switching power supply is provided with a tap exchanger 9 for structuring a conversion ratio control means in combination with a controller 8 and controls the tap exchanging operation of the tap exchanger 9 with a control signal from the controller 8. This conversion ratio control means controls the conversion ratio between the input voltage and conversion voltage by the converter 3 corresponding to amplitude of the input voltage. In the switching power supply, when an input voltage is small, the coiling ratio is increased with the tap exchanger 9 and when an input voltage is large, the coiling ratio is reduced.  Thereby, the ON duty of the switching transistor TR1 is reduced, for example, to 50% which is the optical control value of the power supply and thereby any input voltage can be converted to the predetermined output voltage V0 to improve the power supply efficiency.
