1. What is the Inductor Current Formula?

The inductor current formula calculates the current flowing through the resonant inductor in a resonant converter. It represents the relationship between load current, maximum current, angular frequency, and time period in the resonant circuit.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ I_L = I_{load} - I_{max} \times \sin(\omega) \times t \]

Where:

\( I_L \) — Inductor Current (A)
\( I_{load} \) — Load Current (A)
\( I_{max} \) — Maximum Current (A)
\( \omega \) — Angular Frequency (rad/s)
\( t \) — Time Period (s)

Explanation: The formula calculates the inductor current by subtracting the product of maximum current, sine of angular frequency, and time period from the load current.

3. Importance of Inductor Current Calculation

Details: Accurate inductor current calculation is crucial for designing and analyzing resonant converters, ensuring proper component sizing, and maintaining stable operation of the power conversion system.

4. Using the Calculator

Tips: Enter load current in amperes, maximum current in amperes, angular frequency in radians per second, and time period in seconds. All values must be positive numbers.
