Note that in this design provision has been given for three-phase mains voltage rectification but is not tested. 200 to 480 VAC mains input is given to connectors J1 and J3.
What is a digital signal processor (DSP)?
The controller is implemented using a digital signal processor (DSP). The DSP used in the setup is described in this chapter indicating the features unique to the chosen processor. The algorithm used for the controller is detailed with the help of flowcharts. Finally, the interface circuitry between the DSP and the power circuit is described.
How does a DSP work?
The data is processed by a 12-bit pipeline flash analog-to-digital converter (ADC). The A/D unit produces an end-of-conversion interrupt when the data is valid. The start-of-conversion can be coordinated with a PWMSYNC pulse generated in the three-phase timing unit. The inputs to the A/D unit range from OV to +4V. The DSP development board
What is the control strategy for a three-phase UPS?
new control strategy for a three-phase UPS is proposed in this work. The inverter is modeled by a small-signal time averaged plant. Bode plots are used to analyze the stability of the controller. Simulation and experimental results verify the operation of the controller with a balanced resistive load. measurement noise.
