Formula Used in “Flyback Converter Calculator”
The Flyback Converter Calculator is a valuable tool for electrical engineers and hobbyists alike, allowing the calculation of key parameters in designing flyback converters. The standard formula to determine the output voltage and other essential parameters in a flyback converter is:
Vout = (Vin × D) / (1 – D)
Where:
D = Duty cycle, expressed as a decimal (D = Ton / Ttotal)
Step-by-Step Breakdown of the Formula
To better understand the formula and how to use it, let’s break down the calculation process:
- Determine Input Voltage (Vin): This is the voltage supplied to the flyback converter.
- Calculate Duty Cycle (D): The duty cycle can be calculated using the formula D = Ton / Ttotal, where Ton is the time the switch is on, and Ttotal is the total switching period.
- Plug the Values into the Formula: Insert the values of Vin and D into the formula Vout = (Vin × D) / (1 – D).
- Calculate Output Voltage (Vout): Perform the calculation to find the output voltage based on the input voltage and duty cycle.
Example Calculation
Let’s consider a real-world example using the formula to better illustrate how the calculations work.
| Parameter | Value |
|---|---|
| Input Voltage (Vin) | 24 V |
| Time On (Ton) | 0.4 ms |
| Total Switching Period (Ttotal) | 1 ms |
Now, let’s calculate the Duty Cycle (D):
D = Ton / Ttotal = 0.4 ms / 1 ms = 0.4
Plugging the values into the output voltage formula:
Vout = (Vin × D) / (1 – D) = (24 V × 0.4) / (1 – 0.4) = 9.6 V / 0.6 = 16 V
Output Summary
The calculated output voltage (Vout) for this example would be 16 V, making this flyback converter suitable for applications requiring this voltage level.
