Three phase bridge inverter are widely used for ac motor drives and general purpose ac supplies. Fig 1 shows the inverter circuit suppling a star connected load. The circuit consist of three half bridge , which are mutually phase shifted by 2π/3 angle to generate the three phase voltage waves. Fig 1: Circuit configuration of VSI.
system for a three-phase induction motor. It describes hardware and software. The test results obtained on controlled operation. Thus, the PLC correlates and conditions [7, 14]. 2. PLC as a System Controller (I/O) modules.
PLC is an inverter in constant in activated. c) The standard variable speed operation. The induction voltage-constant frequency standard three-phase supply. feedback. On the other hand, operation c) results if the
In this test case, STS is open ( x STS = 0 ) and the inverter caters to the power demand from the three-phase load. The three-phase loads are configured to operate in constant power mode with the current limit of 8 A. Measured data from the spectrum analyser are fetched and plotted for controller performance analysis.
