| Abstract: | A high-performance power supply system for gyroscopes based on TMS320LF2407A is designed.The 3-phase sinusoidal AC output with constant voltage and frequency is accomplished by SPWM technology.This method has the advantages of low power consumption and high integration degree,so that the portability of the equipment can be achieved.A sound failure detection and management circuit is also developed in order to increase the reliability of the system.With a notch filter and a low-pass filter,the switch harmonic component is effectively diminished.The results show that power supply meets the requirements of the gyroscope. |
