Abstract
In order to suppress the second-order ripple voltage of bidirectional isolation DC-DC converter, a second order ripple feedforward phase-shift control with feedback linearization is proposed. Based on the large signal state-space-averaged modeling, this control includes a phase-shift algorithm of feedback linearization and an output disturbance feedforward algorithm. By converting the nonlinear to linear model, the coupling control variable is decoupled. Then the control rules according to this method is derived and designed on programmable logic device. Finally, a small scale single-phase three-level diode-clamped bidirectional isolation AC-DC-DC converter is tested. The experimental results verifies that the proposed control method has better suppression ability of the second-order ripple voltage suppression than conventional PI control and input voltage feedforward control.关键词
