Abstract :
In this paper a novel method of parameters estimation in Buck converter with Digital-PWM control based on Zero Average Dynamic on Error or ZAD strategy is reported. The ZAD strategy has not been reported in adaptive control scheme. The estimation law is based in the Fixed-Point Inducting Control or FPIC technique. In power converters, the load value is usually unknown; therefore a controller with estimation law of the load value is convenient.
