| Abstract |
The well known series resonant DC-DC converter with galvanic insulation realizes
zero current switching (ZCS). Semiconductor losses can be optimized through
changing the blanking time. The use of a transformer with extremely low leakage
inductance (e.g. coaxial winding transformer) leads to an unconventional commutation
process that results in very low switching losses even in non ZCS mode
which will be described in this paper.
This paper compares the semiconductor losses of the different modes of operation
(conventional ZCS, ZCS with increased blanking time and without ZCS) as experimental
result of a 12kW test setup and of a 200kW prototype converter. |
