Features of system structure
Traditional 3 level PWM structure of neutral character for inverting
Simple circuit structure with less component and higher reliability. Higher voltage output can be realized without serial connect of power components
Output voltage wave form is more like sine wave. High harmonic of voltage is less
dv/dt is smaller, no special requirements to motors' insulate performance
Small size and low cost
Performance Features ..............(AC drive)(variable speed drive)(VSD)(frequency converter).............
Function of vector control, V/F control switching, Choose freely according to the using requirement form the 4 mode: V/F control, V/F with PG, seedless sensor vector control, vector control with PG.
