What is the typical power circuit configuration of a VVVF
Drive ?
Answer Posted / sandeep vazhoor
Typical power circuit configuration involves 3 phase diode
rectifier at the input to convert the AC input to DC
voltage, LC or C filter to reduce the ripple in the DC
voltage. 3 phase IGBT inverter stage converts this DC
voltage into variable voltage variable frequency output as
per the desired pattern.

How do i perform grounding of star point of Genset (400V) for making connection with step up transformer of DELTA-DELTA (400V to 20KV) ? while Genset itself has its own neutral and grounding bus bar inside genset breaker box whereas we have another neutral and grounding busbar in synchronizing panel next to genset at maximum distance of 6meter, would someone pls advice if we can only perform neutral grounding in synchronizing panel or should we ground neutral on both places inside genset breaker box and synchronizing panel.

If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
