SMPSs with passive PFC can achieve power factor of about 0.7–0.75, SMPSs with active PFC, up to 0.99 power factor, while a SMPS without any power factor correction have a power factor …
What is the relationship between efficiency and …
A good question! One way of writing the equation for efficiency is: Efficiency = (Output power) / (Output power + losses) For a transformer running at full rated VA, the losses will be constant no matter what the load power factor. However the (tr...
Determining Electric Motor Load and Efficiency
5 to 10 hp; peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50% load. However, the range of good efficiency varies with individual motors and tends to extend over a broader range for larger motors, as shown in Figure 1. A motor is considered
Motor Efficiency and Power Factor - University of Alabama
Electric power consumption is rated power divided by motor efficiency. Rated power depends on class of motor (which considers intended duty). Industrial grade motors usually are rated for continuous duty. Motor efficiency requirements are set by 1992 Energy Policy Act (EPACT), primarily for larger motors as used in industry and HVAC.
