Design of a 4-Phase Intercell Transformer Converter
for a Space Charge Measuring System
This paper presents the design of a power electronics converter to produce strong current pulses (about 400A) in the core of a HVDC cable in order to use the thermal step method to evaluate the ageing state of the dielectric component. The described converter uses a magnetic coupler with intercells transformers and is current controlled. Index Terms—magnetic coupler; intercell transformer; high current pulses; thermal step method; dielectrics.
