System and method using phase detection to equalize power from multiple power sources
TLDR
In this article, phase detection was used to automatically and substantially equalize the currents supplied to a load by each of the variable-frequency power sources, and to cancel a ripple component of the input current drawn by the system.Abstract:
A system and a method may use variable-frequency power sources for supplying power to a load The system and method use phase detection in order to automatically and substantially equalize the currents supplied to a load by each of the variable-frequency power sources, and to cancel a ripple component of the input current drawn by the system First and second power sources supply power to the load The power sources have a similar relationship between their respective variable switching frequencies and the power that they supply to the load First and second switching frequencies of, respectively, the first and second power sources are locked to one another using phase detection to substantially equalize the power supplied to the load by each power source The system and method are advantageously utilized to provide a power factor correction front-end for a switch-mode power supply Power sources with non-linear and/or inverse relationships between power supplied and switching frequency can be used In alternate embodiments power from series power sources is equalized by equalizing voltages supplied by each power source to a loadread more
