The main driving waveform of variable frequency drive is SPWM and SVPWM. The principle of SPWM is simple and easy to implement. It is the most widely used variable frequency driving waveform. But one of its Achilles' heel is its low power supply (only 86%) and its harmonic components. Therefore, the application of the newly developed products is gradually replaced by SVPWM, which has excellent performance. SVPWM is a variable-frequency driven waveform with low frequency and low frequency components, with low switching frequency and small power consumption. At the same time, SVPWM can also combine vector control algorithm to maximize the performance of the equipment. Therefore, more and more frequency conversion equipment is used. -The main use of variable frequency drive drive waveform SPWM and SVPWM are mainly two. SPWM principle of simple, easy, is now the most widely used as a variable frequency drive waveform. But there is a fatal weakness is its power utilization is not high (only 86), large harmonic components. Therefore, in the newly developed products in its application performance is gradually replaced by SVPWM. SVPWM is a voltage utilization, low-harmonic component waveform of variable frequency drive, there are fewer switches, power control features such as power consumption small. At the same time, SVPWM also a very good combination of vector control algorithm to maximize the performance of the play equipment. Therefore increasingly being used by the inverter equipment.
