摘要: | Multiphase boost-type switch-mode rectifiers (SMRs) are often used to improve the efficiency of ac-dc conversion. In particular, the light-load efficiency can be increased by turning off some phases (i.e., phase-shedding operation). To keep the number of feedback signals fixed regardless of the topology phase number N, the interleaved current sensorless control (ICSC) with consideration of the phase-shedding operation is proposed in this paper. In ICSC, no current sensing is needed, and only input and output voltages are sensed. To demonstrate the proposed ICSC, a two-phase boost-type SMR is established for test, and the proposed ICSC is implemented in a field-programmable-gate-array-based system. The provided simulation and experimental results show good performance of the proposed ICSC. |
