SWITCHING POWER SUPPLY

摘要: PROBLEM TO BE SOLVED: To provide a switching power supply provided with what is called ripple percentage reducing circuit that effectively reduces the of current flows into smoothing capacitor at down-stream side rectifier circuit. SOLUTION: This DC indirect conversion type and positioned post-stage secondary transformer. A coil connected in series to pre-stage line capacitor, position where inputted or outputted from COPYRIGHT: (C)2005,JPO&NCIPI
