3 Phase Full Bridge type PWM Based VSI using Transistor Devices Trainer

SKU: 8579 Category:

ADTRON’s Three phase Full bridge PWM based VSI Inverter trainer kit is a self contained standalone unit. It demonstrates the functioning of a PWM VSI Inverter. The circuit consists of a uC based 3 phase Sine wave and Triangular wave generator, Comparator, gating circuit and 3 phase bridge circuit using MOSFET / IGBT. The unit is housed in an elegantly designed cabinet with a well spread intelligently designed circuit layout / block diagram on the front panel. A comprehensive Instruction manual complete with theory, operating details, Observations, and waveforms is provided along with the unit
