| Abstract: | A variable-frequency variable-voltage power supply system is presented based on FPGA. which adopts the FPGA chip EP2C35F672C6.A SPWM （Sinusoidal Pulse Width Modulation） inverter control technology is used in the system, and a variable-frequency variable-voltage sine wave output is achieved. A prototype has been designed. The prototype has a capacity of 10 kVA, and its voltage and frequency are adjustable within the range of 0-250 V and 20-300 Hz.The hardware and software are designed completely. Simulation experiments are done based on the dual closed-loop PID control strategy. The results verify that the system has good dynamic and static performance. |
