hello everyone
0:03
in this lecture
0:04
we will talk about
0:05
full wave rectifiers
0:10
before we start
0:12
we will
0:14
talk about
0:17
the half wave rectifier
0:18
works
0:19
the half wave rectifier
0:22
is a diode
0:26
and a resistor
0:29
and a resistor
0:31
this is the VIN
0:33
the input is sine wave
0:37
this is the modulator
1:41
only half wave rectifier
1:44
that's why it's called half wave rectifier
1:47
because only half wave is used in output
1:52
that's for half wave
1:53
for full wave rectifier, we will use all wave
1:57
that's a full improvement for full wave rectifier
2:04
using full wave rectification
2:08
we will use the full wave rectifier
2:14
we will use the bridge rectifier
2:22
which consists of 4 diodes D1, D2, D3, D4
2:30
we will start to analyze the signal based on the input signal
2:37
we will take this point from 0 to T over 2
2:42
the input signal will be plus or minus
2:47
so the first point will be the input signal
2:50
plus or minus
2:52
this is the input signal from 0 to T over 2
3:27
the diode will be on, and the diode will be reversed
3:33
the diode will be on, and the diode will be reversed
3:39
the diode will be on, and the diode will be reversed
3:47
the diode will be on, and the diode will be reversed
3:50
the diode will be on, and the diode will be reversed
3:51
the diode will be on, and the diode will be reversed
3:53
the diode will be on, and the diode will be reversed
3:56
so we have D1 OFF and D2 ON
4:06
now we have D3 and D4
4:08
since this is a negative pole, it will affect the negative pole on the cathode
4:16
so this diode will be ON
4:19
why? because it is a negative pole on the cathode
4:54
this is the diode
4:55
this is the diode
5:01
this is the diode
5:05
this is the diode
5:06
this is the diode
5:08
this is the diode
