7 Main Features SA Series Generators Overall Efficiency greater than 96% New Stand Alone Generator Hardware Layout New Heating Head hardware layout To minimize the power loss on the capacitor block Automatic Best optimization to load In order to maximize the power transferred to the workpiece Minimum cooling water flow required Independent Generator+Heating Head and Coil cooling circuits. Two independent circuits with specific water flow and water temperature monitoring on each one) Focus on Generator and Coil Efficiency
8 Coil Efficiency Calculation Test Resume: The comparison will be carried out using different coils, and different metals. Coil used for the test Coil 1 Coil 2 Coil 3 Coil 4 Coil 5 Coil # Ø internal [mm] Loops number Copper Tubing [mm] Coil /8 Coil /8 Coil /8 Coil /6 Coil x6 140 mm 118 mm 95 mm Coil Øint Comparison Scale 1:20
9 Coil Efficiency Calculation Each Coil have been connected to a Heating Head (Capacitor Block) and fed by a Function Generator Measured Value: Resonant Frequency V1 (provided by Function Generator) V coil R 500 Ω V1 The Frequency of the Sine Wave Signal, provided by the Function Generator is manually tuned up to the resonant frequency of the L-C system (Head + Coil) V coil In resonant condition the two signals: V coil V1 = V Function Generator are in phase
10 The capacity of the Heating Head is known (i.e. 19 μf) Equivalent Circuit of Heating Head+Coil with no load (1) The resonant frequency is determined when the system is in resonant condition (i.e. 28 khz) So the coil inductive value is calculated by the equation: 1 f resonant = 2π LC L = 1 4π 2 f 2 C = 1 4 3, ( ) V coil = 1,7 uh 19 μ
11 Equivalent Circuit of Heating Head+Coil with no load (2) Using the simulator LTSpice, we insert in the model the R resistor to calculate the losses on coil. The value of R is manually adjusted until the simulator calculates the same V coil as the measured one. R 3.95 m We find R= 3,95 m ohm
12 The head cooling water temperature increment (ΔT 1 ) and the coil cooling water (ΔT 2 ) are measured, by running the generator with the water connection indicated below. Equivalent Circuit of Heating Head+Coil with no load (3) R 3.95 m We calculate ΔT 1 = 2,0 C ΔT 2 = 17,8 C ΔT 1 ΔT 2 Running the same current on L1 and C1 (resonant condition) it means that the losses on the coil are nearly 9 times higher than the losses on the head, in fact ΔT 1 ΔT 2 = 8,9
13 We add the resistor R3 to take in consideration the losses on the heating head. The resistor R2 allow the calculation of the losses on the coil only. The two resistors are in series so: R = R 2 + R 3 = 3,95 m ohm Final Equivalent Circuit of Heating Head+Coil with no load (4) and R 2 R 3 = 8,9 We obtain: R 2 = 3,55 m ohm R 3 = 0,40 m ohm This is the Mathematic Model of the system, with the coil empty. R 2 R 3 = ΔT 1 ΔT 2 = 8,9
14 Now, following exactly the same procedure as before, we insert a metallic piece into the coil (i.e. carbon steel) and we calculate the new mathematic model, the new equivalent circuit Equivalent Circuit of Heating Head + Coil with Load (1) Of course, compared with the previous case (empty coil), now the system works with: - Different Resonant Frequency (a new L value has to be calculated; This is taken in account by paralleling the inductor L2) - Lower V coil (a new R2 value has to be calculated, we add R4 ) To simplify the calculation we consider that R3 remains constant In fact could be slightly affected by the different resonant frequency
15 This is final the equivalent circuit of the system: Heating Head + Coil + Work Piece Equivalent Circuit of Heating Head + Coil with Load (2) Head+ Coil + WorkPiece We underline that the Mathematic model depends on the coil shape and heating head used. It is independent from the Induction Heating Generator used The same procedure has been carried out placing into the coil metallic rods, with exactly the same diameter (Ø85mm) made of: - Carbon Steel - Stainless Steel AISI Copper - Brass

18 Cable Cable Serial vs. Parallel Resonance The Mathematic Models determined are now used to calculate the: - Voltage - Current on the heading head cable to be provided by ideal Generators to deliver 100kW of Power: Ideal Generator Parallel Resonance Generator Head + Coil + WorkPiece Example Coil 1x95 42uF with Cu workpiece Serial Resonance Generator Ideal Generator Head + Coil + WorkPiece Simulating the system in order to absorb 100 kw from the Generator, we measure: - Voltage on the Head Cable= 415 V rms - Current on the Head Cable= 240 A rms We add the resistor (R capacitor) to calculate the losses on the capacitors block Simulating the system in order to absorb 100 kw from the Generator, we measure: - Voltage on the Head Cable= 416 V rms - Current on the Head Cable= 7950 A rms It s absolutely necessary to use a Transformer to reduce the current on the Head s Cable and on the active component as well
19 Parallel Resonance Generator Serial Resonance Generator With this configuration: Simulating the system in order to absorb 100 kw from the Generator, we measure: - Voltage on the Head Cable= 390 V rms - Current on the Head Cable= 268 A rms - Current on the Load = 7380 A rms At the next page is explained how the losses on the Transformer have been calculated With this configuration: Simulating the system in order to absorb 100 kw from the Generator, we measure: - Voltage on the Head Cable= 2500 V rms - Current on the Head Cable= 513 A rms - Current on the Load = 6320 A rms
20 Series Resonant System : Matching Transformer Mathematic Model The magnetic losses (dispersed field) haven t been taken in consideration. So we consider: Reactive Power Transfer=100% Considering Active efficiency = 97% and connecting the transformer to a load that absorbs 6000 A, it means 30kW lost on a 1000 kw load
