1. What is Diode Current of Resonant Converter?

Diode Current resonant converter (DCRC) is a type of dc-dc converter that uses a resonant circuit to achieve zero voltage switching (ZVS) of the switching devices.

2. How Does the Calculator Work?

The calculator uses the Diode Current formula:

\[ Id = Iload - \frac{Vs}{L} \times t \]

Where:

\( Id \) — Diode Current (Ampere)
\( Iload \) — Load Current (Ampere)
\( Vs \) — Source Voltage (Volt)
\( L \) — Inductance (Henry)
\( t \) — Time Period (Second)

Explanation: The formula calculates the diode current by subtracting the product of source voltage divided by inductance and time period from the load current.

3. Importance of Diode Current Calculation

Details: Accurate diode current calculation is crucial for designing efficient resonant converters, ensuring proper component sizing, and achieving optimal performance with zero voltage switching.

4. Using the Calculator

Tips: Enter load current in Ampere, source voltage in Volt, inductance in Henry, and time period in Second. All values must be valid positive numbers.
