Abstract:
1. A system for supplying power to a load, the system comprising: a. a first and a second power source, each having a control system; b. means for detecting a switch-off event in the first power source and subsequently triggering a switch-on event in the second power source, the means comprising means for directly supplying a first signal to both a switch of the first power source and to the control system of the second power source; and c. a feedback mechanism configured to monitor a switching state of the second power source and to continuously adjust a duty cycle of the second power source according to the switching state, wherein the feedback mechanism is further configured to trigger a switch-off event in the second power source when a residual power supply current within the second power source is substantially equal to zero, wherein the first and second power source have similar noise characteristics.
