INTRODUCTION

The Vishay Foil Resistors (VFR) Burden resistor is usually

connected to the output of the power device for the

discharging of the bulk output filter capacitor when it is

charged and connected to a large power source, like an

accumulator or airplane battery. The Burden resistor offers

resistance of a few ohms and prevents the influence of

inrush current to the device that the power unit (power

converter) connects to. Inrush current usually happens

when the battery or accumulators are very large and their

capacity is too high. The Burden resistor is placed across

the output of the current transformer.

THE BURDEN RESISTOR

Current sensing transformers act as current sources and

need a load. A current source is the dual of a voltage

source, and just like you shouldn't short-circuit a voltage

source because it would cause infinite current, you

shouldn't leave a current source open, as it would cause

an infinite voltage. The precision Burden resistor converts

the current to a limited voltage. Typically it is used to

discharge a capacitor when the circuit isn't powered

anymore.

Resistance

Note

To acquire a precision resistance value,

the Bulk Metal Foil chip is trimmed by

selectively removing built-in “shorting bars.”

To increase the resistance in known increments,

marked areas are cut, producing progressively

smaller increases in resistance. This method

reduces the effect of “hot spots” and improves

the long-term stability of VFR resistors.
