It shows flow versus head, efficiency bands and the Best Efficiency Point (BEP), and how power demand changes with flow, as well as Net Positive Suction Head required (NPSHr) and speed or impeller trims. ...
By introducing a functional gene into the cells with these symptoms, researchers hope to correct the inherited gene mutation and potentially cure the disease. ...
The original timber dam was built to supply turbines for shaft power for a number of factories along the river. In 1940, the dam was reconstructed after the catastrophic flood of 1938 damaged the prior dam. ...
Plus, a switch to LEDs comes with added benefits for your facility's working environment by providing a higher quality of lighting which increases safety and productivity. 4. Power Factor Correction Power Factor (PF) refers to the ratio of real power to the apparent power flowing ...
A reliable, continual power supply is critical to any industrial process to prevent costly interruptions. But nowhere is it more critical than in a sterile environment that handles aseptic / Biological manufacturing. An interruption can lead to discarding entire batches of products, potentially costing producers hundreds of thousands of dollars. That’s why an industrial uninterruptible ...
IEC 60364-8-1:2019 is part of the IEC 60364 series of standards and enhances Parts 1 to 7 with the introduction of requirements and recommendations to design the electrical installation, which provides the best compromise between the required level of service and safety and the lowest electrical consumption. It applies to new or existing installations and those under evolution and should be ...
At the fair Smart Production Solutions (SPS) 2019, Siemens is presenting new 3-phase 24-volt power supply units within its Sitop PSU6200 product line, extending the scope of application of its standard power supplies. ...
Furthermore, large-scale capacitors (another energy storage device) can be installed at the plant to correct the power factor, further saving the plant in their electrical charges. ...
Most everyday appliances and commercial tools run on AC power. This is fine if you’re connecting the device to a wall outlet that provides AC power. But what if you want to use power from a DC source, like a solar-powered generator or a car battery? ...
This paper deals with the analysis, design and simulation of power factor corrected (PFC), low crest factor (CF) electronic ballast for a compact fluorescent lamp (CFL). The proposed electronic ballast employs a Cuk buck-boost AC-DC converter as a power factor regulator (PFR) operating in ...
This paper presents a single–stage isolated power factor corrected power supply (SSIPP) fed permanent magnet brushless DC (BLDC) motor drive. An advantage of fast voltage regulation with single voltage control loop of SSIPP is utilised to develop a power factor correction (PFC) ...
A power factor corrected (PFC) bridgeless converter–based computer power supply (CPS) using multioutput flyback dc–dc converter is presented in discontinuous conduction mode (DCM) of operation. ...
In this paper, a new topology of single-phase pulse width modulated (PWM) AC-DC converter is proposed for bidirectional power flow between plug-in hybrid electric vehicle (PHEV) and the grid. ...
A new digitally controlled, bridgeless AC/DC buck converter that operates in discontinuous–input–voltage mode (DIVM) is presented. It inherits power factor correction property and draws continuous input current during conduction period. ...
In this paper, the modular development of a three–phase single stage ac–dc power converter based on single–phase ac–dc isolated full–bridge converter for telecom power supply applications is presented. ...
A diode bridge fed buck half–bridge DC–DC converter fed from single–phase AC mains is used as a single–stage power factor correction (PFC) converter for feeding a voltage source inverter (VSI) based permanent magnet brushless DC motor (PMBLDCM) drive. ...
Compared to conventional buck or boost converters, this topology allows a low current ripple at the input for a relatively low level of the DC–bus voltage. The converter is used as a power factor correction (PFC) circuit for a single–phase rectifier and, based on the obtained model, steady–state analysis is performed and new design criteria were ...
Abstract - Capacitors provide well-known benefits to electric power systems. These benefits include power factor correction, voltage support, release of system capacity, and reduced system losses. ...
The converter core can be transparently embedded inside current mode power factor controller. In this paper, operation of the converter core, auxiliary circuits, and design guide lines are presented. ...
In this paper a power factor correction (PFC) based Zeta converter fed voltage source inverter (VSI) based permanent magnet brushless DC motor (PMBLDCM) drive is employed for an air conditioner and controlled for its variable speed operation towards energy efficiency improvement. A single-phase single-switch AC-DC converter topology based on the ...
