To obtain electrical contacts, either wires were inserted during the fabrication of the legs, or electrochemical deposition was used. The electrophysical properties of thermoelectric legs with different electrical contacts were investigated.

Presented control system allows to combine all these devices into one distributed system per moving to a modular multilevel conversion topology. In order to ensure the flexibility and the ability to operate in any network configurations, the proposed article also considers the use of a proportional-resonant regulator to abandon the use of phase-locked loop frequency and, as a consequence, simplify the control system.
