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. ...
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. ...
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. ...
This paper proposes a non-isolated single-stage high power factor rectifier suitable for applications requiring low-voltage and high-current output. ...
Installation of capacitor banks proved to be cost effective approach to correct power factor in industrial plants. Optimum capacitance value that contributes to the maximum PF improvement varies from one system to another. ...
It compensates harmonic current, reactive power and balances the load along with neutral current compensation. ...
In this paper, a single-phase power factor corrector (PFC) based on the Sheppard-Taylor topology is studied. ...
This paper deals with the modelling, control and design of 18-pulse voltage source converters (VSCs) for high voltage DC (HVDC) transmission system with power quality improvement. A two-level VSC is used to realise an 18-pulse VSC operation with minimum switching loss. ...
