Example energy capacitance

Capacitance comes from the energy equation. The entered capacitance is not used in this mode.

Energy capacitance 40 nF

C_energy = (L_H * I^2) / Delta_V^2. The inductance unit is converted to henry before this equation.

Capacitance used 40 nF

Energy mode uses C = (L * I^2) / Delta_V^2. Entered mode uses the capacitance and unit you selected.

Damping resistance 10 ohm

R = 2 * zeta * sqrt(L / C)

Resistor loss 8 W

P = C * V_peak^2 * f_Hz. Hz, kHz, and MHz are converted to hertz first.

Capacitor voltage rating and resistor power rating need measurement on the real circuit. No switch part number is stored here.

dv/dt 250 V/µs

dv/dt = V_peak / (R * C) in V/s, shown as V/µs (volts per microsecond).

Minimum on time 1.2 µs

t_on = 3 * R * C, shown in µs (microseconds).

Zeta from 0.7 to 1.0 is a usual damping note, not a clamp. The AC power equation is not used because X_c is not defined.
