Simulation of an Inverter Type Single- Phase Arc Welding Machine. By using multisim or proteus.
Construct the circuit in Figure 1 in the Circuit JS simulator. Note that the voltage source is given in RMS. Within Circuit JS while defining the max voltage of the voltage source include “rms” after the number to tell Circuit JS that this is a rms value. Also note that there are additional parameters when instantiating a transformer in Circuit JS. Leave these at the default values. Additionally, transformers may have problems simulating in Circuit JS. Answer the following: 1. From the simulation results, determine the power dissipated in R2 and compare to the expected value from the previous section.2. Change the transformer ratio (“Ratio” as a fraction when you “Edit…” the transformer component) to the value calculated in the previous section to provide maximum power transfer in R2.
