1. What is Power Delivered to Load in Three Phase Uncontrolled Rectifier?

The Power Delivered to Load in a Three Phase Uncontrolled Rectifier is the product of the AC voltage and the average output DC voltage. It represents the actual power delivered to the load circuit in an uncontrolled rectifier system.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{out} \) — Delivery Power (Watt)
• \( V_{ac} \) — AC Voltage (Volt)
• \( V_{dc} \) — Average Output Voltage (Volt)

Explanation: This formula calculates the power delivered to the load by multiplying the AC input voltage with the average DC output voltage of the rectifier.

3. Importance of Power Calculation

Details: Accurate power calculation is crucial for determining the efficiency of rectifier systems, proper load sizing, and ensuring optimal performance of power conversion equipment.

4. Using the Calculator

Tips: Enter AC voltage and average output voltage in volts. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is an uncontrolled rectifier?
A: An uncontrolled rectifier uses diodes to convert AC to DC without any control over the output voltage magnitude.

Q2: Why is three-phase rectification preferred?
A: Three-phase rectification provides smoother DC output with less ripple compared to single-phase rectifiers.

Q3: What factors affect the power delivered?
A: The power delivered depends on the input AC voltage, rectifier configuration, load characteristics, and circuit efficiency.

Q4: Are there limitations to this calculation?
A: This calculation assumes ideal conditions and doesn't account for losses due to diode voltage drops, transformer losses, or other circuit inefficiencies.

Q5: How accurate is this power calculation?
A: For theoretical purposes and ideal conditions, this calculation provides accurate results. For practical applications, additional factors should be considered.
