VFDS Manufacturer

For industrial purpose the power is to be delivered for larger distance hence AC power supply is required to drive the motors. The rectifier in a VFD is used to convert incoming ac power into direct current (dc) power. There are 3 pair of rectifier combination is used for converting 3 phase AC into DC Normally 6,12 or 18 diodes will be used to serve this purpose. Rectifiers can be built using diodes, silicon controlled rectifiers (SCR), or transistors to rectify power. After the power flows through the rectifiers it is stored on a dc bus. The dc bus contains capacitors ...
