Single-phase inverter – UPS

MCM15/EV

Board MCM15/EV investigates the DC-AC conversion process typical of UPS systems, for the generation of a single-phase AC voltage. It is part of the Interactive Practical Electronics System IPES and works in both standard mode (using switches and consulting the handbook) or computerized mode. In this last case, the software version of the handbook inserts automatically circuit variations and faults, enabling the development of lessons even without teacher’s assistance. Pre-assembled electronic components divided into circuit blocks can be interconnected and modified by means of jumpers and connection cables.
