Abstract: A power plant system architecture includes a plurality of battery polarity switching circuits for providing uninterruptible power/voltage to a plurality of loads, each of which is powered by low frequency AC, and which is also powered by a DC voltage. DC voltage is substituted for the AC voltage applied to the load should the voltage polarity processing circuitry in the power plant fail.

Abstract: An improved electronic welding station is disclosed. The welding station provides for an improved arc striking capability by providing a higher arc striking voltage and a large arc striking current and, once the arc is struck, automatically switches over to preselected parameters for conducting the welding operation. Also disclosed are a method for preventing transistor failure due to loads which tend to cause a very large instantaneous current flow and an apparatus for protecting the driver circuit and the remaining output transistors in the event that one of the output transistors should suffer a collector-to-base short. The welding station also describes a method of operating the cooling fan at a speed commensurate with the cooling requirements and periodically reversing the voltage to the cooling fan so as to extend the operating lifetime of the fan brushes. The welding station also has several shutdown circuits which protect the components of the welding station in the event of cooling fan failure or excessive heating of the weld station. The welding station also provides for a shutdown period for cooling off in the event that the maximum allowable instantaneous current is exceeded.

Abstract: A power supply device capable of supplying high DC voltages of positive and negative polarities has a transformer having a primary coil and two secondary coils. A DC current supplied to the primary coil is switched to generate voltages in the secondary coils. These voltages are rectified and smoothed in mutually opposite polarities, and the output voltages are obtained by summing the rectified and smoothed voltages.

Abstract: An electrical apparatus for regulating voltage polarity including a support for slidably receiving one or more carriers therein, with each carrier including circuitry. A positive and negative source of power is associated with the apparatus and each of the carriers includes connector means for coupling each carrier to the positive source of power when the carrier is in a first position, and for coupling each carrier to the negative source of power when the carrier is in a second position. In a preferred embodiment of the invention means are provided for preventing either intentional or accidental movement of the carriers from one of the first and second positions to the other position during operation of the carriers. Preferably a bridging connector is provided for coupling the circuitry of adjacent carriers to each other when the carriers are in a first position coupled to the positive source of power.

Abstract: A relay control circuit is disclosed in which a timer circuit is actuated by a reference clock pulse in synchronism with an AC voltage supplied by a commercial power supply. An output signal of the timer circuit causes current to flow in the coil of the relay thereby to close the contact of a relay. The invention further comprises a polarity-reversing device for reversing the polarity in accordance with the variations in the output signal of the timer circuit. The reference clock pulse is applied to the timer circuit through the polarity-reversing device.
