The OE Calculation Formula is used to determine the efficiency of a process or system.

• OE (Overall Equipment) = (Operating Time - Downtime) / Operating Time

• Operating Time is the total time the equipment is available for production.

• Downtime is the total time the equipment is not available for production.

• OE value ranges from 0 to 1, with 1 indicating perfect efficiency.

• Example: OE = (500 hours - 50 hours) / 500 hours = 0.

A three level inverter topology consists of three voltage levels to generate a sinusoidal output waveform.
