| Abstract: | Frequency conversion and speed governor has gradually focused people's attention upon it for its good property,but the voltage and frequency conversion is the best system in efficiency and property in the system of frequency conversion and speed governor,too. This paper simply introduces the working principle of the device of the voltage and frequency conversion of the Sine Pulse Width Modulation in the system of frequency conversion and speed governor and the generation of the wave of the pulse width modulation of the sine wave. |
