| Abstract: | In order to satisfy the experiment need of the voltage - frequency characteristic for electrical device and the frequency - varied motor, we designed a kind of intellectual variable voltage and variable frequency power supply with the SPWM way. In this paper, the major hardware circuit was given. The operation principle and control strategy of the circuit were expounded. The design principles of the corresponding circuit parameters were also given. The experiment results show the technique requests of the variable voltage and variable frequency power supply for experiment uses are met. |
