Randomized PWM for conductive EMI reduction in DC-DC choppers

In this paper, a comparative investigation of different random modulation schemes against the normal pulsewidth modulation (PWM) for the DC motor drive with step-down chopper (buck) and half-bridge configuration is presented. For this purpose, an experimental setup with DSP2 board has been developed. The board consists of the signal processor TMS320C32 which is suitable for verifying the differ...

Equivalent Circuit Model for Square Ring Slot Frequency Selective Surface

An equivalent circuit model for predicting the frequency response of a square ring slot frequency selective surface (SRS-FSS) for normal incidence is described. The proposed FSS consists of an array of square patches centered within a wire grid. The presented circuit model is formed by the impedance of the wire grid that is parallel with the impedance of the patch array, also the mutual couplin...

Re-using & Re-rating Older Rectifiers with New DC/DC Choppers

The recent development of high power DC/DC converters (more commonly know as Chopper Rectifiers) allows customers the option to keep older rectifier transformers and refurbished systems if reconfiguring or installing new cell line loads. Normally, new cell line impedances would require the replacement of transformer/rectifier equipment. This paper is intended to describe how one can change the ...

A New Circuit Topology for Open Circuit and Short Circuit Fault Tolerant Dc - Dc Converter

This paper describes a new design for a fault tolerant Hbridge dc-dc converter. Open circuit and short circuit fault tolerance is achieved using multilevel converter topology in combination with pulse width modulation control strategy allowing a large set of converter switching states to produce bidirectional power flows at any required output voltage. If two switches fail at particular instant...
