For the reactive power and harmonic current caused by nonlinear loads closed to pulse-width modulation(PWM)rectifiers

a PWM rectifier with LC-series filter and its current iterative learning control method are proposed. Here

PWM rectifier can not only provide loads with energy

but also compensate for reactive and harmonic current caused by the nonlinear loads. It can achieve effective integration of the rectification function and power compensation. The LC-series filter is adopted to make the capacitor bear the fundamental voltage

so that it can be directly connected to the power grid. In order to overcome inertia damping of the LC-series filter

a deadbeat control method based on the iterative learning algorithm is proposed for integration with the performance of feed-forward and feedback control to effectively improve the response speed and control accuracy of the system. The convergence condition of the algorithm is also derived. Simulation and experimental results have verified the correctness and validity of the proposed structure and method.
