Abstract
The invention provides control methods and systems for harvesting energy from a variable-output power apparatus. One or more variable-output power elements configured for producing energy are used as input to a power regulation circuit operably coupled between the power elements and a load. One or more power signals in the circuit are monitored and the power regulation circuit output is dynamically adjusted based on the one or more monitored power signals. According to aspects of the invention, the output duty cycle or frequency may be adjusted in response to monitored parameters.
