| Abstract |
A comparative study of three suitable power electronic converter topologies is made in order to feed an
electromagnetic contactor, increasing the command voltage range. It is intended to use a unique coil for
most usually commercial voltages available, with economical benefits, regarding production and stock
costs. DC and AC inputs are allowed.
A comparison among the different topologies is done, regarding the input-output voltage relationship and
the system power losses.
The control system is presented using sliding mode control theory and evolving the converter topology with
best performance. |
