Viper12a Induction Calculator

Formula

The maximum inductance \( L_{\text{MAX}} \) is calculated using the formula:

\[ L_{\text{MAX}} = \frac{(V_{\text{DC(min)}} \cdot D_{\text{MAX}})^2}{2 \cdot P_{\text{IN}} \cdot f_{\text{SW}}} \]

Example Calculation

Let's assume the following values:

Minimum Input Voltage \( V_{\text{DC(min)}} \) = 12 V
Maximum Duty Cycle \( D_{\text{MAX}} \) = 50%
Input Power \( P_{\text{IN}} \) = 5 W

Step 1: Convert the duty cycle to a decimal:

\[ D_{\text{MAX}} = 50\% = 0.5 \]

Step 2: Substitute the values into the formula:

\[ L_{\text{MAX}} = \frac{(12 \cdot 0.5)^2}{2 \cdot 5 \cdot 60000} = \frac{(6)^2}{600000} = \frac{36}{600000} = 0.00006 \, \text{H} = 0.06 \, \text{mH} \]
