Comparative control analysis of the Vienna rectifier based on its averaged model
This paper presents a comparative evaluation of two multiple-loops duty-cycle-based control schemes applied to a three-phase three-switch three-level boost-type rectifier. The control laws are both elaborated on the basis of a state-space averaged model of the converter, expressed in the synchronous rotating frame. On the one hand, a control scheme that uses linear regulators is designed by using ...

Non-isolated single stage PFC rectifier for wide-input large step-down voltage applications
This paper proposes a non-isolated single-stage high power factor rectifier suitable for applications requiring low-voltage and high-current output. The proposed converter integrates two buck-boost converters with a buck converter. As a result, the proposed converter can operate over a wide range of input voltage with extended low output voltage capability, making it suitable for universal input ...

What is an Alternator? How does it Work?
Electricity in your car is as important as it is in your home. All the vehicles have a dedicated device, alternator, which runs all the electronic parts. Find out what exactly an alternator is how does it work to provide electricity to our vehicle. What is an alternator? The alternator is an electric generator that converts mechanical energy into electrical energy, particularly in the ...

Modelling and control of a variable speed wind turbine driving doubly fed induction generator using three–level PWM converter
The aim of this researcher is to develop a complete wind central model driven doubly fed induction generator (DFIG) which feeds an AC power grid. For that, two–pulse width modulated (PWM) voltage converters are connected back to back between the rotor terminals of DFIG and the utility grid via a common DC link, in there, our contribution will appear in the utilisation of three levels voltage ...

Three–level NPC rectifier–based midpoint converter–fed SRM drive
This paper deals with a three–level Neutral Point Clamped (NPC) rectifier–based midpoint converter–fed Switched Reluctance Motor (SRM) drive. The three–level NPC rectifier for midpoint converter–fed SRM drive is used for improving power quality at AC mains and to balance the DC link capacitor voltages. The proposed three–level NPC rectifier is designed, modelled and its performance simulated ...

Analysis, design and control of a two stage improved power quality telecommunication power supply
This paper deals with the power quality improvement at the utility interface of a telecommunication switched mode power supply (SMPS) of 12 kW rating. The first stage of this SMPS consists of a 6–pulse diode bridge converter that performs ac–dc conversion yielding an unregulated dc voltage. In the second stage, two boost rectifiers are connected together which feed to a boost dc–dc full bridge ...

Did You Know? Switch Mode Rectifiers, Calculating Float Voltage & C-Rates
Switch Mode Rectifiers The most common technology in use today for stationary battery charging is the Switch Mode Rectifier (SMR). They offer a higher efficiency and are smaller and lighter than the legacy Ferro Resonant and Silicone Controlled Rectifier (SCR) types. More importantly, they are easily field-swappable. Did you know that the SMR was first invented 110 years ago and was a ...

Difference between Frequency and high-frequency forklift
First, the difference between the high frequency and power frequency Workers Electric Reach Truck charger power devices operating in the linear state, which means he used up the power device is always at work, and therefore would result in low efficiency of his work, generally in the range of 50% to 60%, have to say he is good linear power. Linear power supply works, so that he must change from ...
