pulse transformer X isolation transformer

isolating pulse transformer

Are these two names the same thing? A pulse transformer is the same thing as isolation transformer?

mago,
They are not the same, although a pulse transformer can also be an isolation transformer. An isolation transformer has two electrically isoltaed windings for the purpose of providing a ground (common) reference on the secondary side that is elctrically isolated from the primary. A pulse transformer is a high frequency transformer that is designed with minimum inter-winding an intra-winding capacitance, so that there is minimum ringing on the output when a waveform with sharp rising and/or falling edges is applied.
Regards,
Kral

Another thing is that the pulse transformer is specified by time domain parameters.
Audio transformers are specified by frequency domain, impedance levels, and power.
Power transformers are specified by voltage and current at each winding as well as the operating frequency.

Pulse Transformer

It's core is made of Ferrite and
is used for high frequency applications and
the turns ratio is one to many or vice versa



Insulation Transformer

It's core is made of silicon steel and
is used for power frequency applications and
the turns ratio is one to one

They are not the same, although a pulse transformer is used for electrical isolation betn high power and low power circuits .
Pulse transformer is used for providing triggering to SCRS in power electronic applications.
It comes 1:1( 1 primary, 1 secondary), 1:1:1: (1 primary, 2 secondaries for bridge appllications)
An isolation transformer has two electrically isoltaed windings for the purpose of providing a ground (common) reference on the secondary side that is elctrically isolated from the primary.
A pulse transformer is a high frequency transformer that is designed with minimum inter-winding an intra-winding capacitance, so that there is minimum ringing on the output when a waveform with sharp rising and/or falling edges is applied.
