ee_student Posted August 14, 2003 Report Share Posted August 14, 2003 hello!I want to have a vvvf driver circuit (& programme) of a 3-phase induction motor from a 1-phase a.c. sourse!!!please!!!thank you!!! Link to comment Share on other sites More sharing options...
marke Posted August 16, 2003 Report Share Posted August 16, 2003 hello ee_student I am sure that you are not the only one to want a complete design!!The basic principles for a three phase input three phase output and a single phase input three phase output inverter are the same. The only difference is that the single phase input unit has a single phase bridge rectifier and a much larger storage capacitor while the three phase input inverter has a three phase rectifier and a smaller storage capacitor. In both cases, the output voltage is limited to the input voltage unless an additional transformer is used.Best regards, Mark Empson | administratorSkype Contact = markempson | phone +64 274 363 067LMPForum | Power Factor | L M Photonics Ltd | Empson family | Advanced Motor Control Ltd | Pressure Transducers | Smart Relay | GSM Control | Mark Empson Website | AuCom | Soft Starters Link to comment Share on other sites More sharing options...
