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:

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