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 ...

Single–phase switch mode high power quality cycloconverters
In this paper, we propose three new single–phase switch mode cycloconverters. Instead of simple switching scheme of P– and N–controlled rectifier–converters, high frequency switching of full bridge rectified outputs has been used with the help of SMPS topologies. This enables the input current switching at high frequencies and effective current shaping using passive filters. The input supply is ...

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 ...
