| Abstract: | The advantage and disadvantage of sample-hold strategy based double-state switching power amplifiers are analyzed, and a method of using the PLD (programmable logic device) is proposed in the design of sample-hold strategy based tristate switching power amplifiers for active magnetic bearings. The logic function of PLD is designed, and the simulation waveform of the inside function is given. Compared with traditional design methods, this design has the advantages that the number of devices is cut down, the circuit is simplified, the volume is reduced, the design cost is reduced, the design efficiency is improved and the reliability of the power amplifier system is enhanced. |
