20130015830 | Switching Power Supply Having Separate AC And DC Current Sensing PathsAANM Zhang; JindongAACI FremontAAST CAAACO USAAGP Zhang; Jindong Fremont CA US - In a current mode controlled switching power supply, current through the inductor is sensed to determine when to turn off or on the switching transistors. The inductor current has a higher frequency AC component and a lower frequency DC component. The AC current feedback path, sensing the ramping ripple current, is separate from the DC current path, sensing the lower frequency average current. Separating the current sensing paths allows the signal to noise ratio of the AC sense signal to be increased and allows the switching noise to be filtered from the DC sense signal. The gain of the DC sense signal is adjusted so that the DC sense signal has the proper proportion to the AC sense signal. The AC sense signal and the DC sense signal are combined by a summing circuit. The composite sense signal is applied to a PWM comparator to control the duty cycle of the switch. | 01-17-2013 |
