6 FAQs about [High voltage resistors in energy storage systems]

What is a high energy disk resistor?

Standardized for a 50 W resistor in std. air, 1.2/50usec. pulse width High Energy Disk resistors are most often used for low repetition rate discharge, crowbar, pulse shaping or other impulse duty. In practice, a single resistor disk or combination is usually selected to yield no more than 100°C rise for the expected applied energy.

How to design with high-voltage resistors?

Optimized strategies prioritize the definition and testing of key components early in the design cycle. High-voltage resistors are one such component. Here are 10 tips for designing with high-voltage resistors. Optimized strategies prioritize the definition and testing of key components early in the design cycle.

Why do high voltage resistors need a high voltage rating?

It is sometimes the case that designers looking at high-voltage resistors are doing so because their circuits must withstand high-voltage transients. If the continuous voltage stress does not call for a high-voltage rating, it may well be the case that a low-voltage but surge-tolerant part is the best solution.

How much power do high energy disk resistors dissipate?

Continuous power dissipation for High Energy Disk resistors is a function of mounting method used. In free air, .25 watt per cm² of exposed surface area is a conservative rule of thumb. Thus, a 50mm disk with both faces and the periphery exposed could easily dissipate 20 watts.

What is a silicone resistor used for?

They are ideally suited for use in pulsed power systems, where these resistors distribute energy uniformly throughout their structure for low thermal stress. The standard, high-temperature silicone coating enhances high voltage performance in air. Optional configurations optimize performance in other gaseous or fluid dielectrics. Max.

How much heat can a resistor withstand?

In practice, a single resistor disk or combination is usually selected to yield no more than 100°C rise for the expected applied energy. Because of the large mass, a relatively long cooling time is required between pulses, or additional heat capacity must be allowed for.
