A didactic configurable converter for training on inverter and chopper topologies

Didactic equipment for a power electronics laboratory is described. The equipment has a synoptic panel with power and signal modules and can be externally configurable as any one of a class of chopper and inverter topologies. Multipurpose pulse-width modulation command modules are provided for single-phase and three-phase inverters as well as for five different types of chopper. Each power section is internally self-protected. Isolated output signals of current and voltage measurements are also provided adding versatility for use either in didactic or research applications. The implementation of a prototype allowed experimental confirmation of the expected performance.
