A Field-programmable Gate Array (FPGA) is an integrated circuit designed to be configured by the customer or designer after manufacturing—hence "field-programmable". The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC) (circuit diagrams were previously used to specify the configurati...

An FPGA-based reconfigurable system may contain boards of FPGAs which are reconfigured for different applications and must work correctly. This paper presents a novel approach for rapidly testing the configuration in the FPGAs each time the system is reconfigured. A low-cost configuration-dependent test method is used to detect faults in the circuit. The “original configuration” is modified by ...

electric and hybrid electric vehicles are attractive candidates for sustainable transportation due to its higher efficiency and low emission. the critical choice on the electric motors is its capability of motoring and regenerative braking characteristics. switched reluctance machines are viable candidate as with proper control and extended constant power range operation replacing the multi-gea...

Shaft position sensing is an essential part of switched reluctance (SR) motor drive In order to synchronize the pulses of phase current with the period of rising inductance of the proper motor phase. Direct sensors such as, Hall effect and optical encoder are commonly used in SR motors. The purpose of this paper is to present an indirect shaft positioning sensing known as "sensorless " control ...

In this article, a step-up seven-level inverter supplied by single dc source suitable for renewable energy application is presented. Forming the desired output realized charging capacitors and synthesizing them based on switched-capacitor concept. This structure praised ability of sensorless voltage balancing capacitors, reducing control complexity to produce bipolar staircase waveform. It also...

This article presents a circuit configuration and control for coil-array wireless power transmitters. The target coil arrays have coils that are uniform in shape dimensions regularly arranged with an angular interval of 120°. system has three-leg half-bridge inverter, which simultaneously feeds the three transmitter. It can deal more than by adding switch set between inverter coils. to cancel m...

An electronically tunable universal voltage-mode biquadratic filter with single input and four outputs using one differential difference current conveyor transconductance amplifier (DDCCTA), two resistors and two grounded capacitors is proposed. All the five standard biquadratic filter functions; lowpass (LP), bandpass (BP), highpass (HP), bandstop (BS) and allpass (AP), can be obtained from th...
