Reference-Input-Based Imaginary Axis Current Estimation Method for DQ Control Strategy in Single-Phase PWM Converters

For $dq$ control strategies in single-phase pulse width modulation (PWM) converters, the $eta-mathbf{axis}$ current must be created by imaginary axis current estimation (IACE) Carts methods.The estimated error of the $eta-mathbf{axis}$ current during the transient process causes $d-q$ axis current loops to be incompletely decoupled, thereby affec
