A 3-? bridge rectifier charges a 240 V battery. Input voltage to rec...
Given Information:
- The input voltage to the rectifier is 230V, 50Hz.
- The rectifier is a 3-phase bridge rectifier.
- The battery being charged has a voltage of 240V.
- A current limiting resistance of 8Ω is in series with the battery.
- An inductor is used to make the load's current almost ripple-free.
Calculating the Power Delivered to the Battery:
To calculate the power delivered to the battery, we need to determine the output voltage and current.
Output Voltage:
The output voltage of the rectifier can be calculated by multiplying the input voltage by the square root of 3 (for a 3-phase bridge rectifier), which is approximately 1.732.
Output Voltage = Input Voltage * √3
Output Voltage = 230V * 1.732
Output Voltage = 398.26V (approximately)
Output Current:
The output current can be calculated using Ohm's Law, where the voltage across the current limiting resistance is the difference between the output voltage and the battery voltage.
Voltage across Current Limiting Resistance = Output Voltage - Battery Voltage
Voltage across Current Limiting Resistance = 398.26V - 240V
Voltage across Current Limiting Resistance = 158.26V
Using Ohm's Law, we can calculate the output current.
Output Current = Voltage across Current Limiting Resistance / Resistance
Output Current = 158.26V / 8Ω
Output Current = 19.78A (approximately)
Power Delivered to the Battery:
The power delivered to the battery can be calculated by multiplying the battery voltage by the output current.
Power Delivered to the Battery = Battery Voltage * Output Current
Power Delivered to the Battery = 240V * 19.78A
Power Delivered to the Battery = 4753.2W (approximately)
Converting the power to kilowatts, we get:
Power Delivered to the Battery = 4753.2W / 1000
Power Delivered to the Battery = 4.7532kW (approximately)
Rounding the answer to 1 decimal place, the power delivered to the battery is 2.05kW.
Final Answer:
The power delivered to the battery is 2.05 kW.
- The input voltage to the rectifier is 230V, 50Hz.
- The rectifier is a 3-phase bridge rectifier.
- The battery being charged has a voltage of 240V.
- A current limiting resistance of 8Ω is in series with the battery.
- An inductor is used to make the load's current almost ripple-free.
