Power supply controller
First Claim
1. A control system in combination with an inverter power supply comprising:
- input means for measuring at least one operational signal from within the inverter power supply, the input means producing at least one operational value based on the operational signals measured;
controller means for generating a set of operational information elements, each operational information element being calculated by the controller means according to a predetermined formula based on at least one of the operational values received from the input means, wherein the controller means periodically samples each operational value and updates the set of operational information elements;
display means for providing operator interface for the controller means, the display means including visual indicates means, the visual indicating means including a first indicating area for sequentially displaying the value of one operational information element at a time from the set of operational information elements; and
sequencing means in the controller means for alternating the operational information element value being displayed in the first indicating area on a cyclical basis by sequentially displaying the value of one operational information element for a predetermined period of time and then automatically changing the first indicating area to display a different operational information element value.

Abstract
A control system for an industrial inverting type power supply is disclosed which provides for both operational control and a diagnostic capability for the power supply. The operational control aspects includes measuring and displaying a plurality of operational signals from within the power supply, and for providing several automatic modes of operation for the power supply. The diagnostic aspects of the control system include measuring and displaying a plurality of diagnostic values, particularly the measurement of several waveform characteristic values of the switching waveform of the power supply. Other diagnostic capabilities include a set of remote inputs, each of which, when activated, triggers an entry into a history table, thereby maintaining a record of remote input activations. Each remote input may also be configured with a descriptive message to be displayed on an operator display and a code which specifies the action that is to be taken by the control system when that remote input is activated. A short detection circuit is also included which operates when the power supply is stopped to test the switching elements of the power supply for shorts.
