Considering that the state equations of peak current-mode (PCM) controlled buck light-emitting diode (LED) driver with proportion-integration (PI) compensator are third-order singular matrices with maximum rank 2, it is not invertible and may lead to non-convergent problem under certain circuit parameters. Therefore, an improved discrete-time model...
Constant on-time (COT) control has been widely applied in industrial applications due to its fast transient response. However, the conventional COT controlled buck converter has poor output-regulation accuracy. A new control method, called improved COT (ICOT) control, that provides both high output-regulation accuracy and fast transient response fo...
