Pulse width limitations 

 

 
Maximum pulse width, which the driver is able to provide at its output, isn’t fixed, but depends 
on driver’s modification, operating current, load voltage and input voltage. 
 
Approximate formulae to estimate the maximum pulse width in a certain regime is 
E

MAX

=I*V*T

MAX

, where T

MAX

 is a maximum pulse width PDD-300 is able to provide with 

current I and voltage V at its output. E

MAX

 is a maximum extractable energy, which varies from 

~200J in standard modifications to ~300J in long pulse modifications. 
 
Examples of pulse width curves for different drivers and different loads are given below. More 
detailed information can be requested from the manufacturer. 
 

PDD-300-100A-30V 

PDD-300-150A-25V 

 

 

Maximum pulse width - around 65ms at maximum 

current and voltage. Even longer at smaller currents 

and/or voltages 

Maximum pulse width - around 45ms at maximum 

current and voltage. Even longer at smaller currents 

and/or voltages 

 

PDD-300-100A-50V

 

PDD-300-100A-20V

 

 

 

Maximum pulse width - around 35ms at maximum 

current and voltage. Even longer at smaller currents 

and/or voltages. 

Maximum pulse width - around 100ms at maximum 

current and voltage. Even longer at smaller currents 

and/or voltages.
