| Abstract: |
| The mechanism of low-frequency ripple current suppression is analyzed in detail and in terms of control strategy and topology optimization, the existing methods for suppressing the low-frequency ripple current of two-stage single-phase inverter are discussed respectively for four sections: DC input, front-stage DC/DC converter, DC-bus capacitor branch and back-stage inverter. The basic concept of low-frequency ripple current suppression for single-phase inverter is analyzed, the technical principles, advantages and disadvantages of existing methods are summarized, their characteristics are compared and its future research direction is pointed out. As an example, an experiment for a new Boost inverter verifies the effectiveness of new control strategy for low-frequency ripple current suppression. |
