This is what is known as "power factor correction" (PFC).
This ensures there is no sign of flicker or strobing across the entire dimming range, while still maintaining a high power factor.
The authors of the cited references claim to have achieved the power factor of their designs exceeding 0.99 and the efficiency of about 85 %-90 %.
At the opposite end of the spectrum, you don't want to exceed a given Power Factor by more than is necessary, and most standard ammo is a lot snappier than you want or need.
That is, it eliminates the need for extra sensors, reduces control complexity, reduces the cost, and the results of simulation shows that the power factor for a BLDC motor drive is improved near unity with the help of three-level boosting PFC converter and this control method is implemented in a FPGA-based system, and all the provided results demonstrate the proposed method.
Not only are issues of energy efficiency important, but also durability, maintainability and impact on system power factor should be considered in motor selection.
There are other less common or premium types of electronic lighting ballasts that minimize both the undesirable displacement and distortion power factors, resulting in a power factor that approaches, but does not quite reach unity (1.00) power factor; typically near 0.90 or greater.
Arithmetic operations for the active, reactive, and apparent powers and the power factor can be obtained from (3) to (6), respectively.
The drive's unique design supports higher voltage motors without the need for an output transformer, and avoids many problems associated with older variable frequency drive designs, such as low efficiency, low input power factor, and output harmonics.
They specialise in a technology called "Power Factor Correction" which can considerably reduce industrial energy bills whilst recovering its initial cost within two years.
However, the phasing back of the semiconductor-controlled rectifier (SCR) in the DC drive, which is used to control speed, creates a poor power factor at low speeds.
The PFC (power factor correction) circuit is, therefore, studied and developed in the past two decades [4-6] to meet the IEC (International Electrotechnical Commission) requirements in the harmonic current standard [7].
