Technical FAQs 4

What is a power resistor?

A power resistor is a specialized passive component designed to dissipate substantial electrical energy as heat. Unlike standard resistors used in low-power or signal-level circuits, power resistors handle higher currents and voltages, often in the range of tens to thousands of watts.

What are the different types of resistors?

These requirements may include filter resistors, snubbers, gate resistors, bleeders, balancing resistors, voltage dividers, braking/regenerative braking resistors, power factor control, surge current protection, pre-charge resistors, and even current shunts. Here we will discuss the various resistor solutions.

What makes a good power resistor?

High-quality resistors incorporate materials and construction techniques that enhance heat dissipation, such as anodized aluminum housings, thermal paste compatibility, and robust ceramic cores. PEC’s PHBR Series includes power resistors from 315W to 1700W, featuring finned housings for superior cooling and long-term stability under full load.

How long does it take a resistor to reach 60vdc?

With 1600Ω as U0 the closest standard resistor value, the circuit reaches 60VDC within 4.5 seconds. Using Ohm’s Law, the peak current is 625mA. Consequently, the power resistor must have a power rating of 625W, (see Figure 3 power at t = 0 seconds).
