Abstract: A power combining technique includes receiving a first voltage at a first input and a second voltage at a second input. The power combining technique further includes combining, with at least two power converters, power received from the first and second inputs into a single power rail. A power balancing technique further includes controlling the at least two power converters such that a first one of the power converters outputs an amount of current to the single power rail that is proportional to and/or equal to the amount of current output by another of the power converters.

Abstract: Described examples include a method of controlling a power converter including executing a plurality of cycles. Each cycle includes turning on a first switch during a first period, the first switch coupled between a power supply and an output inductance; turning on a second switch during a second period, the second switch coupled between an output inductance and ground; turning on a third switch at a first time during the second period, the third switch coupled between the power supply and an auxiliary inductance; and turning on a fourth switch on at a third time after the second time, the fourth switch coupled the auxiliary inductance and ground. The second period ends at a third time period after the first time based on a later of an overlap time and a current through a switch connected to the second switch current handling terminal exceeding a threshold current.

Abstract: Example embodiments of the systems and methods of non-invasive continuous adaptive tuning of digitally controlled switched mode power supply based on measured dynamic response disclosed herein rely on time domain measurements for the tuning rather than on frequency response to automatically tune the system for stability and good dynamic performance. In particular, an algorithm directly measures overshoot and settling time to transients. Using this information, the algorithm minimizes both overshoot/undershoot and settling time by adjusting the parameters of a digital compensator. Since time domain measurements are directly used, the implementation does not require an additional perturbation in the system that otherwise would be necessary.

Abstract: In described examples, a system (e.g., a light-emitting diode dimmer system) includes a switching device coupled to a switching controller. The switching controller generates a control signal, which includes a low frequency signal (e.g., for controlling a dimming function) and a switching signal. An active electromagnetic interference filter (AEF) is coupled to the DC source. An active shunt is coupled to a power input node of the switching device and is configured to selectively couple a shunt current to the power input node of the switching device in synchronization with the low frequency signal (e.g., which can reduce, if not also eliminate, a saturation time of the AEF and improve the performance of the AEF).

Abstract: Timing circuitry causes: a first closed signal on a first switch control output before a signal on a second switch control output changes from a second closed signal to a first open signal; the first switch control output to provide a second open signal after a first selected time after the second switch control output changes from the second closed signal to the first open signal; and a third switch control output to provide a third closed signal a second selected time after the first switch control output changes from the first closed signal to a third open signal. A beginning of the first closed signal to a beginning of the first open signal is based on a later of: a current through a switch connected to the second switch control output exceeding a threshold current; and a clocked time after the beginning of the first closed signal.
