   A Method to Analyze the Current Ripple Distribution in Multi-drive Systems
By DOENITZ Steffen; HINZ Hartmut [View]
[Download]

Abstract: This paper presents a method to analyze the current ripple distribution in a multi-drive system by analyzing the DC bus impedances. By using this method the choice of the right DC link capacitor and the related switching frequency of the power electronic can be supported.

   Addressing the Topologies, Converters, and Switching Devices for Intermediate Bus Architectures
By BROWN Jess [View]
[Download]

Abstract: The distributed voltage in Intermediate Bus Architectures (IBAs) is by no means standardized in the power electronics industry. This paper investigates the efficiency of both the front-end converter and the point-of-load (POL) converter commonly used in IBAs, when implemented with various distributed voltage levels and MOSFETs with different device parameters.

   The DC-Link Capacitor Current in Pulsed Single-Phase H-Bridge Inverters
By RENKEN Folker [View]
[Download]

Abstract: In case of controlling a pulsed single-phase H-bridge inverter with two and three voltage levels the capacitor currents in the dc-link circuit are calculated analytically. For these calculations first a sinusoidal modulated voltage and sinusoidal current at the output of the inverter are presupposed. Afterwards the additional load of the dc-link capacitors caused by harmonic currents of the output filter circuit is examined. For this reason the individual harmonics of the dc-link current with sinusoidal and with overlaid harmonic output currents are calculated with help of spectral analysis. At last the influence of the switching processes to the dc-link circuit load is discussed. The theoretically determined currents in the dc-link capacitors are compared with several practical measurements.
