A New Pulsating Power Elimination Method for Single-Phase PWM AC/DC Converters with Minimum Voltage and Current Stress
An inherent problem of single-phase rectifiers is the existence of a pulsating portion in the input power, which pulsates at twice the grid frequency. If this pulsating power is transferred to the DC-link, it causes a significant amount of second-order harmonic at the output voltage. Since in many applications, such a high level of DC oscillation is not acceptable, so the pulsating power must b...
متن کاملAn Improved Phase-shifted Carrier Pwm for Modular Multilevel Converters
The modular multilevel converter is improved topology for high-voltage, high-power applications since the cascaded sub modules can generate high-voltage waveforms with excellent harmonic performance at low switching frequencies. Many publications have been presented on the modulation and control of this converter type, some of which are based on phase-shifted carrier modulation. This paper pres...
متن کاملA Novel Stand-Alone Single-Phase Induction Generator Using a Three-Phase Machine and a Single-Phase PWM Inverter
A new type of single-phase stand-alone induction generator using a three-phase induction machine and a single-phase voltage-source PWM inverter is introduced. The generator scheme is capable of producing constant load frequency with a very well regulated output voltage. A small lead acid battery and a single-phase full diode-bridge rectifier are used to feed the inverter. The inverter feeds one...
متن کاملThree-Phase to Single-Phase Matrix Converters: New Topology Based on New Control Method
In this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. In addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. In the proposed control metho...
متن کاملSmall-Signal Models of Some Basic PWM Converters
The paper presents the full-order small-signal models of some basic PWM converters (Cuk, Sepic and Zeta) with discontinuous inductor current mode (DCM). The derivation procedure is based on the small-signal PWM switch model in DCM and converter topologies derived from their original topologies. The small-signal characteristics of these converters are presented in symbolic forms. Such models can...
