ZVS Induction Heater + Tank Calculator Tool

Let us build a full ZVS driver + tank circuit simulator super useful for trying different values of voltage, frequency, inductor, capacitor, and seeing how your ZVS-based induction heater behaves.

What This Simulator Does:

It Calculates:

• Resonant frequency (f)
• Required inductance (L)
• Tank current (approximate)
• Reactive power (Q-factor)
• Heating efficiency range estimate
• Shows warnings if parameters are unsafe

How to Use this Induction Heater Calculator

1. Enter your values: Supply Voltage in V DC, Capacitance in microfarads, and Inductance of the work coil in microhenries.
2. Click Run Simulation to view the calculated frequency, peak voltage, circulating current, and reactive power.

Manual Calculation Example Using the default values:

Voltage = 24 V, Capacitance = 0.33 microfarads (0.33 x 10^-6 F), Inductance = 7.6 microhenries (7.6 x 10^-6 H).

Step 1: Resonant Frequency Formula: f = 1 / (2 * pi * sqrt(L * C)) L * C = 2.508 x 10^-12 sqrt(L * C) = 1.58366 x 10^-6 2 * pi * 1.58366 x 10^-6 = 9.9504 x 10^-6 f = 1 / 9.9504 x 10^-6 = 100,498 Hz (or 100.5 kHz)

Step 2: Peak and RMS Tank Voltage Peak Voltage = pi * V = 3.14159 * 24 = 75.4 V RMS Voltage = Peak Voltage / sqrt(2) = 75.398 / 1.4142 = 53.31 V

Step 3: Inductive Reactance Formula: X = 2 * pi * f * L X = 2 * 3.14159 * 100498 * (7.6 x 10^-6) = 4.80 Ohms

Step 4: Circulating Tank Current Formula: I = V_rms / X I = 53.31 / 4.80 = 11.1 A (RMS)

Step 5: Tank Reactive Power Formula: P = V_rms * I P = 53.31 * 11.11 = 592 VA
