  • Method and apparatus for regulating an electrical power source based on global and local maximum load power
    Patent number: 10256743
    Abstract: A method for regulating an electrical power source, comprising the steps of detecting for one or more predetermined conditions associated with a load power of the electrical power source, whereupon the one or more predetermined conditions is detected, acquiring electrical characteristics of the electrical power source to determine a global maximum load power value arranged to approximate a true maximum load power of the electrical power source, and processing the global maximum load power value to determine a local maximum load power value of the electrical power source, wherein the local maximum load power value is arranged to be more accurate in approximating the true maximum load power of the electrical power source when compared with the global maximum load power value.
