Abstract

The invention discloses a novel DC-to-AC conversion circuit and method. The circuit comprises a DC-to-AC module, a synchronous motor and a single-chip microcomputer. The input end of the DC-to-AC module is connected with a direct-current power supply, and the output end is in connection with the synchronous motor; the DC-to-AC module is also connected with the control end of the single-chip microcomputer; according to the invention, the working principle is simple, the cost is lower, and the motor works more stably; compared with the prior art, a higher-power load can be driven, a digital waveform with a certain frequency is provided by using the single chip microcomputer, the direct current 12V is converted into the digital waveform with a frequency to simulate an alternating current waveform, and then the synchronous motor is driven to work.

Description
