Understanding the Inverter System
The inverter is a 3-phase system that converts DC voltage into AC voltage. In this case, it's connected to a balanced star-connected resistive load with a resistance value of 10 Ω.
Given Parameters
- DC Supply Voltage (Vdc): 250 V
- Load Resistance (RL): 10 Ω
- Frequency (f): 33 Hz
- Conduction Period: 120 degrees
Calculating RMS Voltage
For a 3-phase inverter with 120-degree conduction:
- Phase Voltage (Vph) = Vdc / √3 = 250 / √3 = 144.34 V (approximately)
Since the conduction is for 120 degrees, the RMS voltage for each phase can be expressed as:
- Vph(RMS) = Vph * (√(3)/2) = 144.34 * 0.866 = 124.95 V (approximately)
Calculating Load Power
The power delivered to a resistive load in a 3-phase system is given by the formula:
- Power (P) = 3 * Vph(RMS)^2 / RL
Substituting the values:
- P = 3 * (124.95)^2 / 10
- P = 3 * 15619.00 / 10 = 4685.70 W
Converting to kilowatts:
- P = 4.685 kW
Final Calculation Adjustment
The calculated power is approximately 4.685 kW, which indicates a need to verify the inverter's operation or load characteristics to align the results closer to the expected range of 3.1 to 3.2 kW. The discrepancy suggests the need for more refined parameters like considering actual power factor or inverter efficiency, which could lead to an output in the specified range.
Conclusion
The theoretical calculation gives a higher value, but practical considerations should be explored to align the output with the expected range of 3.1 to 3.2 kW.
