Abstract:
1. A system for providing power from a power source to a load, the system comprising, a converter for providing output power from the source to the load by different modes, the modes comprising direct energy transfer for efficient direct connection of the source to the load and peak power tracking, the peak power tracking mode including a buck peak power tracking submode for transferring maximum power from the source to the load by adjustment of the converter operating point, and a boost peak power tracking submode for transferring maximum power from the source to the load by adjustment of the converter operating point, the converter comprising at least four switches driven by at least four switch signals, an output sensor for determining output power from the converter, and a processor for monitoring the output power for autonomously selecting one of the modes at any one time and for providing switch signals for controlling the converter, wherein the system operates in direct energy transfer mode to maximize the power delivered to the load at a time when source power in peak power tracking mode exceeds source power in direct energy transfer mode by an amount X, where X is greater than zero, and power losses between the source and the load exceed X in peak power tracking mode.
