hello everyone
in this lecture
we will talk about
full wave rectifiers
before we start
we will
talk about
the half wave rectifier
works
the half wave rectifier
is a diode
and a resistor
and a resistor
this is the VIN
the input is sine wave
this is the modulator
only half wave rectifier
that's why it's called half wave rectifier
because only half wave is used in output
that's for half wave
for full wave rectifier, we will use all wave
that's a full improvement for full wave rectifier
using full wave rectification
we will use the full wave rectifier
we will use the bridge rectifier
which consists of 4 diodes D1, D2, D3, D4
we will start to analyze the signal based on the input signal
we will take this point from 0 to T over 2
the input signal will be plus or minus
so the first point will be the input signal
plus or minus
this is the input signal from 0 to T over 2
the diode will be on, and the diode will be reversed
the diode will be on, and the diode will be reversed
the diode will be on, and the diode will be reversed
the diode will be on, and the diode will be reversed
the diode will be on, and the diode will be reversed
the diode will be on, and the diode will be reversed
the diode will be on, and the diode will be reversed
so we have D1 OFF and D2 ON
now we have D3 and D4
since this is a negative pole, it will affect the negative pole on the cathode
so this diode will be ON
why? because it is a negative pole on the cathode
this is the diode
this is the diode
this is the diode
this is the diode
this is the diode
this is the diode
