  • Rectifier control system for a DC power plant system
    Patent number: 4451773
    Abstract: A DC power plant system has the operation of its individual rectifiers controlled by a stored program control system for the purpose of optimizing power efficiency. Load power requirements are compared with rated capacities of operating rectifiers of the system and individual rectifiers are turned on or off so that the plant efficiency is always maximized. Rectifiers are selected for turn on and off in the basis of their rated power capacity and their accumulated operating times.

  • Uninterruptible power supply with load regulation of standby voltage source
    Patent number: 4313060
    Abstract: An uninterruptible power supply utilizes a controlled ferroresonant regulator to derive a regulated DC voltage from a primary AC source. A reserve source of DC power is coupled to the output through a DC voltage regulator which is activated when the DC output voltage of the power supply drops below a predetermined threshold.

  • No-break AC power supply
    Patent number: 4010381
    Abstract: An uninterruptable power supply supplies a regulated output by utilizing a ferroresonant transformer. Two independent inputs are connected to the transformer; one input is connected to a commercial AC line signal source, the other input is connected to a battery energized static inverter circuit. The AC line source normally supplies the output power. A phase control system monitors the phase of the regulated output signal and constrains the static inverter to run in phase with the output. The phase and magnitude of the AC line signal are monitored. If the magnitude of the AC line drops significantly, the static inverter is constrained to operate in phase with the AC line signal wherein the inverter and AC line both share to contribute power to the output load. If the AC line signal fails, the static inverter operates independently and supplies all of the output power to the load.

  • Inrush current limit circuit with reset response to lowered input voltage
    Patent number: 3935527
    Abstract: A converter circuit includes an inrush current limit circuit to limit the initial transient surge of inrush current to a power supply upon the initial application of voltage to the power supply input. After the initial start-up transient inrush current surge, the inrush current limit circuit is switched out of the input signal path to reduce power dissipation during normal steady state operation of the circuit. If the input voltage magnitude decreases significantly at any time, the inrush current limit circuit is reset to limit any further current surges.
