Apparatuses and systems enable power transfer from one or more energy sources to one or more loads. The input power from the energy sources may be unregulated, and the output power to the loads is managed. The power transfer is based on a dynamic implementation of Jacobi's Law (also known as the Maximum Power Theorem). In some embodiments, the energy sources are selectively coupled and decoupled from the power transfer circuitry. In some embodiments, the loads are selectively coupled and decoupled from the power transfer circuitry. Power transfer to the loads is dynamically controlled.

Multi-source, multi-load systems with a power extractor

In some embodiments, a power extractor utilizes power transfer circuitry with analysis circuitry to detect a power slope and to control the magnitude of the current in response to the detected power slope. The power analysis circuitry may increase the current as long as the power slope shows an increase in power and may decrease the current as long as the power slope shows a decrease in power. The magnitude of the current is responsive to the duty cycle of the switching circuitry and to the detected power slope. Other embodiments are described and claimed.

Power extractor detecting power and voltage changes

In some embodiments, a power extractor's control loop detects changes in power and controls the duty cycle of the switching circuitry in response to the detected changes in power, thereby controlling the power transfer. The control loop may include a signal generator to control the duty cycle, and the frequency of the generated signal may be changed to optimize the energy transfer efficiency. The switching circuitry may control the rate at which circuits store and release the energy in response to the control signal and thereby seek to obtain a rate of storage and release that results in no detected changes in power. Other embodiments are described and claimed.

Power extractor with control loop

In some embodiments, an apparatus or system may include multiple power extractors each coupled to a different power source. The power extractors may be in parallel or in series. The extractors and power supplies may be joined together in a frame. A power source and power extractor may be included in an integrated circuit. Other embodiments are described and claimed.

System and apparatuses with multiple power extractors coupled to different power sources

In some embodiments, a power extractor may operate such that the source impedance and the load impedance may have various values. The power extractor dynamically matches the impedance of the source and the load for the maximum transfer of power. The power extractor includes detection circuitry to continuously detect power changes, and is operated such that impedances of the power extractor between the source and load are dynamically changed in response to the detected power changes. The power extractor may then match an impedance of a power source to the impedance of a load. Other embodiments are described and claimed.

Power extractor for impedance matching

In some embodiments, a power extractor operates in a manner to obtain more power transferred from the source to the load than typically is obtained without the power extractor. The power extractor may perform universal impedance matching as this is seen from either the power source or the load. This impedance matching allows the power source to provide an optimal amount of power transfer that is greater than would be able without the impedance matching. The power extractor transfers power between two nodes and may be operated so that the power transferred is dependent on continuously detected power changes, and the voltage and current at the first and second nodes are unregulated. Other embodiments are described and claimed.
