1. What is Displacement Power Factor?

Displacement Power Factor Semi Converter is the power factor due to the phase shift between voltage and current at the fundamental line frequency in a semi converter based circuit.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Delay Angle Semi Converter — Refers to the angle at which the thyristor is triggered to start conducting current in semi converter based circuit (in radians)

Explanation: This formula calculates the displacement power factor based on the cosine of half the delay angle in a semi converter circuit.

3. Importance of Displacement Power Factor

Details: Accurate displacement power factor calculation is crucial for power system analysis, harmonic distortion assessment, and efficient power conversion in semi converter circuits.

4. Using the Calculator

Tips: Enter the delay angle in radians. The value must be a non-negative number representing the triggering angle of the thyristor.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of displacement power factor values?
A: The displacement power factor ranges from 0 to 1, where 1 indicates perfect power factor (no phase shift) and 0 indicates complete phase opposition.

Q2: How does delay angle affect power factor?
A: As the delay angle increases, the displacement power factor decreases due to increased phase shift between voltage and current.

Q3: What is the difference between displacement power factor and total power factor?
A: Displacement power factor only considers the fundamental frequency component, while total power factor includes harmonic distortion effects.

Q4: When is this formula applicable?
A: This formula is specifically designed for semi converter circuits with constant load current operation.

Q5: What are typical delay angle values in practical applications?
A: Delay angles typically range from 0 to π radians (0° to 180°), depending on the control requirements of the semi converter.
