ELECTRONIC FEEDBACK CONTROL

摘要

The present invention relates to electronic feedback control for an electrical system. In one aspect there is provided an electrical processing device for performing feedback control for an electrical system, wherein the electrical processing device is configured perform steps of: (a) receiving a parameter value from the electrical system indicative of a parameter of the electrical system; (b) comparing the parameter value to a reference value to generate an error polarity indicative of a polarity of an error between the parameter value and reference value; and (c) causing generation of a switched-mode signal in accordance with the error polarity, wherein the pulse width modulation signal is provided as feedback to control the operation of the electrical system.
