Abstract :
It is shown that two Schwarz converters in cascade provide a very reliable 20 kHz source that features zero current commutation, constant frequency, and fault-tolerant operation, meeting requirements for spacecraft applications. A steady-state analysis of the converter is presented, and equations for the steady-state performance are derived. Fault-current limiting is discussed. Experimental results are presented for a 900 W version, which has been successfully tested under no-load, full-load, and short-circuit conditions.<>
