Design of Portable Inverter Power for Gyroscopes based on DSP

A high-performance power supply for gyroscopes based on TMS320LF2407A is designed,with constant 3-phase sinusoidal AC output by SPWM technology.The portability of the equipment can be achieved by the advantages of low power consumption and high integration degree.A sound failure detection and management circuit is also developed to increase the reliability of the system.With a notch filter and a low-pass filter,the switch harmonic component is effectively diminished.The experimental results show that the voltage stability is less than 0.28% and the frequency stability is less than 0.05%,which meet the requirements of the gyroscope.
