00:06This video will analyze natural commutation converters or rectifiers.
00:11which consist of an electrical circuit that converts electrical energy from one form to another.
00:19We have the following image which describes how an alternating current source transforms
00:24the energy in the different types of converters, and the different loads.
00:31For the circuit to be simulated, we have a single-phase half-wave rectifier,
00:36This means that it transforms alternating current of constant voltage into direct current of constant voltage.
00:42Made up of diodes, in this case we could use SCR, and its name is a controlled rectifier,
00:48These constitute irreversible assemblies.
00:54To simulate the circuit, we need a wave generator, in this case a sinusoidal and a square wave generator.
01:02followed by two 330 ohm resistors,
01:12two SCRs, in C-A08BT1G,
01:24a 100,000 end-wave inductor,
01:29and a resistance of 220 ohms; later the resistance will be changed in order to specify the wave cutoff.
01:51Now we will make the connections.
02:20For connections to the oscilloscope,
02:22We have the probe set on land.
02:39Channels 1 and 2 are connected in series with the inductor.
02:53Channel 3 is connected to the sinusoidal signal.
03:02We already observed the behavior in the simulation,
03:05This transforms alternating current of constant voltage into direct current of variable voltage.
03:11Formed by thyristors, at a constant voltage, we have the wave cutoff.
