A high-power and high-precision electronic load based on a virtual instrument

Traditional electronic load has some deficiencies such as low accuracy, low dynamic range, and low intelligence, etc. In order to overcome these issues, this paper is introducing a high-power and high-precision electronic load system, proposing a solution for further combining the high-power and the high-precision, developing a user-computer interface based on a virtual instrument technology, and an embedded programming for the testing system. The electronic load system is designed based on LabView, single chip microcomputer and MOSFET that ensure high testing accuracy, large dynamic range and secondary development function.
