Synchronous mechanical rectifier-inverter — II

The embodiment of the general method for obtaining successful commutation in a synchronous mechanical rectifier-inverter by the use of harmonic voltages is described in this paper, which reports the results of tests on a 50 kw experimental unit. This type of rectifier is shown to have satisfactory characteristics of power factor, regulation, overload capacity, and commutation under transient load conditions, and has good efficiency, especially at low voltages and light loads.
