摘要： Systems, methods, and devices relating to the use of multiple DC power generation sources with DC/DC converters to thereby provide AC power suitable for provision to a power grid. Multiple DC power generation sources are each coupled to an input stage with a DC/DC converter. All the DC/DC converters in the multiple input stages are controlled by a single digital controller. Within the single digital controller are controller sub-blocks, each of which generates control signals for a specific DC/DC converter. Each controller sub-block provides multiple functions for improving the performance of the system as a whole.

摘要： To reduce gate-drive losses caused by high switching frequency operation, embodiments herein include a novel resonant gate driver circuit for driving switches. This gate drive circuit can include a simple two-half-bridge structure. A coupling inductor of the resonant gate driver circuit can provide energy circulation between gates of high and low side switches and also works as a voltage-boost transformer. According to one configuration, the resonant gate driver circuit can be extended to drive two MOSFETs with a common ground. Both theoretical and simulation results for the new resonant gate driver circuit illustrate increased efficiency via lower switching losses.

摘要： A power supply configuration includes a monitor circuit to monitor an output voltage and output current of a power supply. The output voltage can be used to supply power to a dynamic load. The power supply varies a rate of changing an adaptive output voltage reference value that tracks the output voltage. Based on a comparison of the output voltage with respect to the adaptive output voltage reference voltage value, a controller associated with the power supply controls switching operation of the power supply to maintain the output voltage within a voltage range. For example, modifying the rate of changing the adaptive output voltage reference value over time depending on current operating conditions of the power supply changes a responsiveness and ability of the power supply to provide current to the dynamic load.

摘要： A power supply circuit includes one or more reference voltage generators that respectively generate a time-varying output voltage reference value as well as a corresponding time-varying output current reference value. During operation, the reference voltage generators produce different step values for the time-varying output voltage reference value and the corresponding time-varying output current reference value over time such that the power supply has a substantially fixed output impedance value. According to one configuration, the time-varying output voltage reference value tracks the power supply output voltage. Via a comparison of the power supply output voltage with respect to the adaptive output voltage reference voltage value and a comparison of the output current to the corresponding time-varying output current reference value, a controller circuit associated with the power supply controls switching operation of the power supply to regulate the power supply output voltage.
