CAPACITIVE POWER SUPPLY SYSTEM

摘要

The system (3) has positive terminals and negative terminals connected to a supplying network (A) supplying an alternative voltage, and an input capacitor (C1) connected to one of terminals. A rectifier module (33) generates a direct voltage on continuous bus from the alternative voltage. A bus capacitor (Cb) is connected between a positive line (31) and a negative line (32) of the bus. Junction FET type bidirectional semi-conductor transistors (T1, T2) are mounted in series and are manufactured by a material having a high bandgap energy, where the transistors are cabled in limiting current. The transistors are made of silicon carbide and gallium nitride.
