Many power ICs use frequency jitter, which spreads a control signal's spectrum, to control EMI (electromagnetic interference). If you need to add frequency jitter to power ICs that control three-phase ...

One of the hidden complications of upgrading grain drying and handling systems is providing enough electricity to power the new larger electric motors. Electric motors that are larger than 15 hp ...

When selecting a diesel generator, one of the most critical decisions you must make is choosing between a single-phase and a three-phase generator. This choice affects how your generator delivers ...

Stepper motors are a subject that keeps recurring. This little circuit changes a clock signal (from a square wave generator) into signals with a 90-degree phase difference, which are required to drive ...

Variable frequency drives (VFDs) offer the best system efficiency in heating and cooling systems, especially if they have an accurate and very wide range of speed control. To obtain truly variable ...

The AMT49413 can be used as part of three-phase motor drive systems with maximum supply voltages up to 50V. One feature of the devices is a charge pump regulator that provides adequate (>10V) gate ...

Today, compressor overheating is one of the HVACR industry’s most serious field problems. Compressor overheating is usually caused from high compression ratios. High compression ratios can be caused ...

The average efficiency of an internal combustion engine in real-world operation is measured at around 20 percent. 80 percent is lost as waste heat, of which only a small proportion is useful in winter ...
