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.
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.
Choosing a power resistor isn’t just about picking a resistance value off a datasheet. Multiple factors affect the resistor’s performance, safety, and lifespan. Power Rating (Wattage): The maximum continuous power the resistor can safely dissipate. Resistance Value (Ohms): Determines how much current the resistor limits or energy it dissipates.
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.
