Lecture 23: Three-Phase Inverters
One might think that to realize a balanced 3-phase inverter could require as many as twelve devices to synthesize the desired output patterns. However, most 3-phase loads are
DC bus pre-charging techniques
Why Pre-Charging An Inverter’S Dc-Bus?Pre-Charge Circuit DescriptionPrinciple of OperationState Machine ImplementationOther ApplicationsAs already explained, the order of opening/closing contactors is absolutely essential to avoid potentially damaging current flows. It is also important to take into account the time that each contactor requires for its operation. For this purpose, the implementation of a state machine is recommended. This also facilitates the grid connection/disconSee more on imperix.comnext.gr
