Dc to Dc Buck Converter Circuit #buckconverter
Transcript
00:00DC to DC buck converters are suitable for circuits that step down the input DC voltage.
00:06The circuit includes a transistor, a diode, an inductor and a capacitor.
00:10At the initial moment when switch S1 is closed, current begins to flow in the load.
00:16Due to the presence of inductance, electrical energy is stored in the form of magnetic energy
00:20in a magnetic field.
00:22However, according to the Lenz's law, as the magnetic flux in the coil increases, a reverse
00:28voltage is produced in the coil.
00:31The change in resistance produces a voltage that is opposite to the applied voltage.
00:36In this way, the supply voltage is equal to the inductance, the sum of the voltage at
00:41both ends and the voltage across the load.
00:45The load voltage is less than the supply voltage.
00:48If we control the switching time of the transistor, we can get different output voltages.
00:54Our purpose is achieved.
00:56The duty cycle is equal to the ratio of the output voltage to the input voltage.
01:01Once the transistor is turned off, the inductor coil discharges outward like a power source
01:07and converts the previously stored magnetic energy into electrical energy.
01:13According to the Lenz's law, the inductor coil resists changes in the magnetic field
01:18and produces the same voltage as the applied voltage.
01:22In this way, the diode is forward biased and begins to conduct until the energy in
01:28the inductor coil is fully released.
01:31The current stops flowing when the energy in the inductor is completely released.
01:35The diode is reverse biased and is in the cut-off state.
01:40At this time, the transistor S1 is immediately closed and the cycle begins again.
01:46Using this method, the target voltage can be used to obtain a continuous output.
