1 f SCR Parallel Inverter 8524

Categories: Power Electronics


                         ADTRON’S 1f SCR Parallel Inverter is a self – contained stand – alone unit useful in the study and demonstration of the principle and working of a Single Phase SCR Parallel Inverter. It consists of a DC Source, Triggering Circuit of variable frequency, Class ‘C’ Commutation and AC output. The load capacity of the Inverter is 500 VA. The unit is housed in an elegant metal cabinet, with a well spread intelligently designed circuit layout on the front panel. Multi – coloured Test Points are provided at various stages in the circuit to observe the waveforms and voltages. It is strongly supported by a comprehensive instruction manual complete with theory and operating details.
