00:02This video will discuss the industrial electronics of author José Rodríguez, whose
00:08The application occurred in power electronics; we have the action scheme of the electronics
00:12In terms of power, we have an input voltage from the grid, and we have the processing of
00:17power, this is controlled by a signal controller, preferably an oscillator
00:22The 555 monostable square wave timer, and as an output we have a load that could well be
00:27A lamp, or a resistor. The classification of energy forms varies.
00:34Types such as rectifier, its input is alternating current and its energy flow to us
00:39In the conversion of direct current, we have the inverter, which is of direct current.
00:43With alternating current, a push button or chopper for direct current as a load, we have
00:49a small DC motor, and we have the converter cycle, are the different
00:53Among families of power converters, we have mixed frequency converters.
01:00It is with a DC voltage link, inverter rectifier, or current source, the switch
01:06It offers the user the voltage interruption of a semiconductor, turning it on and off.
01:11On/Off, okay, now we have the circuit to simulate which consists of a transistor, the controller
01:19It will be the 555 monostable multivibrator, to perform the measurements on a load, in this case a resistor.
01:26The voltages to be obtained and the pulse width modulation of the 555 are also shown.
01:42To perform the simulation, we will control the converter circuit; we have
01:48from the 555 timer, then some resistors, then a capacitor or capacitors, its measurement is one
02:02microfarad, and 10-farad, a direct current power supply
02:10of 5 volts, ground or earth, at the output we have an LED indicator, together
02:26with a resistance of 220 ohms, and we make the connection, here warn that in order not to make a mistake
02:32In the connection, we will need to investigate the pinout of the 555 timer, and we continue
03:02performing the required configurations and connections.
03:51Let's remember that the IC555 timer is an integrated circuit, a chip, used in the generation
03:57of timers, pulses, and oscillations. The 555 can be used to provide
04:04time delays, such as an oscillator, and as a flip-flap integrated circuit.
04:09Its derivatives provide up to 4 timing circuits in a single package.
04:33Thank you.
04:35Thank you.
04:35Thank you.
04:42Thank you.
04:54Thank you.
05:07We need to find the following curve of the initial voltage, and together with the timer
05:12the 555, with a pulse and square-shaped oscillations.
05:18Now let's look at the power circuit, which consists of a TIP 47 transistor, a 1N4407G diode,
05:30a 100 MHz inductor, a 1 Kilo Ohm resistor, and a 330 Ohm resistor.
06:05From the base of the transistor we connect a resistor.
06:18From 330 Ohms, at the output of the 555, from the collector we connect to the 5 volt current source
06:31continuous, the emitter will be connected to the diode in parallel with the 100 MHz inductor.
06:49Once the design is done, we center it, and from the oscilloscope we take the serial measurement
07:02With the 330 Ohm resistor, the other channel will take the measurement from the inductor.
07:14Now we will move on to the simulation, a DC to AC converter as well
07:19He is known as an investor.
07:21A single-phase transistor inverter conducts for half a period.
07:24The output voltage is alternating current; the output voltage can be controlled by varying
07:29the conduction time of the transistors.
07:47Here on the oscilloscope we present both channel 1 and channel 2 in a better way.
07:522, we configure their positions and the division by volts, in the section division per second
07:57We control the wavelength.
