Toroid

November 14, 2018 Steve Dick, K1RF - gnarc.org

For dissipated power in the toroid(s), it makes a big difference. At 50 watts continuous and 75% efficient toroid(s), power dissipation in the toroid is 12.5 watts. At 50 watts continuous and 85% efficient toroid(s), power dissipation is 7.5 watts: 60% of the 75% efficient toroid! CW duty cycle is ~ 44% of continuous power

Chapter 11 Inductance and Magnetic Energy

inductance of the toroid in this limit has the same form as that of a solenoid. Example 11.4 Mutual Inductance of a Coil Wrapped Around a Solenoid A long solenoid with length l and a cross-sectional area A consists of N1 turns of wire. An insulated coil of N2 turns is wrapped around it, as shown in Figure 11.2.4. 11-8

THEORY AND APPLICATION OF CONDUCTIVITY

One toroid is the drive coil, the other is the receive coil. The sensor is immersed in the conductive liquid. The analyzer applies an alternating voltage to the drive coil, which induces a voltage in the liquid surrounding the coil. The voltage causes an ionic current to flow proportion-
