The main advantage of asymmetrical multilevel inverters is the optimization of levels with a minimum number of power supplies. However, this optimized multilevel system still needs a large number of isolated and floating DC supplies, which makes these converters complicated to implement in electric vehicles (EVs), because the system will require many independent battery packs. In this paper, a very...
This paper proposes a novel control method for an interface converter that is using an indirect matrix converter (IMC) with a DC power supply. The proposed converter is constructed based on an indirect matrix converter and a converter that combined the function of a boost type converter and a step-down type converter. The proposed converter connects an active snubber to the DC link part of IMC along...
In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is proposed. Compared to other DC power supplies which using the conventional matrix converter, the proposed topology possesses high quality input current and output voltage, adjustable input power factor, and no large energy storage component. Moreover, it has more advantages than other proposed...
High Power telecommunication power supply systems consist of a three-phase switch mode rectifier followed by a DC/DC converter to supply loads at 48 VDC. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor with high total harmonic distortion (THD). In this paper, a DC power supply based on matrix converter with reduced number of switches is proposed...
