Abstract: A control for an inverter operable for converting direct voltage and current to alternating voltage and current. The inverter includes a plurality of electrical valves each operable to conduct current in a single direction upon the application of a positive voltage in the forward direction and the receipt of a trigger pulse. The control provides successive trigger pulses for commutating the current between successive valves at predetermined electrical firing angles and includes a voltage-time area calculating circuit for calculating the maximum permissible firing angle which will permit successful commutation. An inverter commutation failure prevention circuit is coupled to the alternating current network for detecting abnormal voltage conditions and for producting a control signal functionally related to any deviation in the alternating voltage from the expected voltage condition. The control is responsive to the control signal for reducing the electrical angles of the trigger pulses provided to the valves.

Abstract: Methods and apparatus for metering electrical energy are disclosed in an electronic meter which includes a first oscillator for generating a first clock signal within a first accuracy and a second oscillator for generating a second clock signal within a second accuracy. A processor, operable in relation to a clock signal, measures time and periodically compensates for the accuracy of the first oscillator. The first clock signal is used for measuring time when power is applied to the meter and the second clock signal is used by the processor for measuring time when power has been removed from the meter. The accuracy of the first oscillator is compensated periodically in relation to a compensation factor stored in memory. In one embodiment, the processor includes a counter for counting from a first value to a second value in response to the first clock signal. In such an arrangement, the processor substitutes the first compensation factor for the first value. The meter can further include a timer, wherein the processor substitutes the first compensation factor for the first value in response to the first timer. The processor also is shown to implement a process for compensating for the accuracy of the second oscillator. This process compensates for the accuracy of the second oscillator in relation to the first oscillator. To this end, the process calculates a second compensation factor. The second compensation factor is determined when power is applied to the meter, wherein after power has been removed and restored, the second compensation factor is used to compensate time measured in relation to the second oscillator during the period power had been removed.

Abstract: Methods and apparatus for switching a load between first (P) and second sources (A) is shown to include first (32) and second (42) solid state switches connected to the load. First (30) and second (40) mechanical breakers are connected between the switches and the sources so that each source is connected to the load through a circuit breaker and solid state switch. A controller (50) is connected to sense the voltage from the first (P) and second (A) sources. The controller (50) is connected to the first (32) and second (42) switches and the first (30) and second (40) mechanical breakers. The controller (50) senses the phase difference from the voltages from the first (P) and second (A) sources. The controller (50) causes the first (30) and second (40) mechanical breakers to open and close in response to sensing the phase difference between the sources. The first (30) and second (40) mechanical breakers can include medium voltage vacuum breakers. In a preferred embodiment, when the controller (50) senses that the phase differences between sources is more than 30 degrees out of phase, the controller (50) will open the circuit breaker (40) connected to the alternate source (A). In this manner voltages stress on the solid state switching devices is minimized.
