    Under the National Electrical Code, an engineer designing a motor branch circuit has the option of selecting motor short circuit protectors (MSCP's), one of two kinds of circuit breakers, or one of several classes of fuses for his short circuit protection means. In making his decision, he evaluates initial cost, convenience, degree of protection, replacement cost, etc. This paper outlines these tr... View full abstract»

    This paper discusses the design, development, and successful use of an electronic instrument for the evaluation of grease noise in electric motor grade ball bearings. No evidence was found that grease noises were harmful to the proper mechanical operation of the ball bearings. However, it did segregate ball bearings that would, in a motor, produce psychologically irritating noises due to grease th... View full abstract»

    The use of switching regulator circuits at high power levels and high frequencies requires careful examination and control of the power dissipation during switching, which may be the dominant loss. In this paper it is shown that it is possible to remove most of the switching losses from the switching transistor with two networks, each containing three components: an inductor or a capacitor, a diod...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2717 KB)

    A new regulated dc to dc converter circuit gains several advantages over conventional approaches by separating the pulsewidth control function from the inverter. The distinguishing feature of the new circuit is the relocation of the principal filter inductor from the rectifier output to the inverter input. This departure from the conventional use of a shunt capacitor at the inverter input yields a... View full abstract»

    Pulse-position modulators are used for remote sensing of analog signals in a high-voltage constant-current dc power supply for a wideband submarine cable system. The pulse-position modulators translate the sensed analog signals into the time domain in the form of time delayed pulses. The transfer characteristics of the modulators are linearized and made insensitive to clock frequency and other sou... View full abstract»

    Designers of high-power circuits have not previously been able to quantitatively estimate the design tradeoffs which are available between the blocking voltage, current density, and turnoff time of a thyristor. In this paper, a new tradeoff relationship is derived by combining simple relationships from well-known device theory. The constants in this relationship are empirically adjusted to correla...

    In spite of its importance in the rating and reliable application of power diodes and thyristors, the computation of instantaneous junction temperature has been a poorly understood and generally dreaded process among equipment designers. Under many practical circumstances, it has only been feasible by means of lengthy computer programs. View full abstract»
