"There are at present four common methods of con
verting the alternating current into direct current.
These are in order of use, the motor generator set,
the rotary converter, mercury vapor rectifier and the
Murphy rectifier. A short description of these and
connections for the last two will be given."--p.2
This paper describes an inverter design which provides voltage
regulation against variations in both the input voltage and load impedance.
This design modifies the so-called parallel inverter, which
consists of two silicon controlled rectifiers (SCRs) operating in a
push-pull arrangement, to include a third regulating SCR. This
regulating SCR is...
In advanced hybrid electric vehicle development, performance and dependability are essential considerations in the design process. High efficiency is crucial in a successful design and fault tolerance is necessary to provide limp-home capability under faulted operating conditions. The reduction of electromagnetic interference is mandatory to reduce interference in communications and...
An instrument which measures current from D.C. to 50 megahertz
by clipping a transformer core around a current carrying conductor
is discussed. A Hall device, which is installed in the core cross-section, detects the flux in the core. This Hall device in conjunction
with an amplifier is used to null...
Since this treatise is to deal only with the
construction of one special machine it is unnecessary
to go into an extended discussion of dynamo electric
machinery in general. Some of the parts common to all
electric machinery of this character will be mentioned
and then a short account of...
