| Abstract: | A new nonlinear control scheme for PWM converter is proposed on the basis of one-cycle control. By means of correcting the initial reset voltage of the integrator and input reference voltage, the defect existent in the one-cycle control is overcome and the ability of switching error correction is improved so that the steady-state error is essentially eliminated. It is verified by theoretical analysis and simulation test that the scheme is feasible. |
