In this paper, the proposed hardware logic type digital controller for on-board SMPS which has a very small time-delay in control loop has been described. Some experimental has been done including evaluation of load current change and frequency characteristic of open loop transfer function. These results have been revealed that the proposed circuit could be suppressed the time delay to sub — micro...
The matrix converter (MC) is an attractive topology for the more electric aircraft because of its high-power density and bidirectional power flow features. One of the challenging issues in MC is the current commutation. The commutation process in a matrix converter (MC) is more complex as compared with that of the traditional AC-DC-AC converter due to the lack of natural free-wheeling paths. Multi-step...
The paper presents a Maximum Power Point Tracking (MPPT) controller for a multi-channel (N-Channel) Photovoltaic (PV) solar system which requires only one voltage sensor and no current sensors. The N-channel Load Voltage Single-Sensor MPPT (LV-SS-MPPT) controller is able to track the MPP of each solar panel using only one output voltage value in the N-channels and is able to provide a very good tradeoff...
