In this paper, an improved hybrid space vector pulse width modulation (HSVPWM) technique is proposed for IM (induction motor) drives. The basic principle involved in the proposed random pulse width modulation (RPWM) cuddled SVPWM is amalgamating the pre-calculated switching timings for various sections of hexagonal space vector boundary and the random selection of carrier between two triangular signals, in order to disband acoustic switching noise spectrum with improved fundamental component. The arbitrary selection between triangular carriers, which is decided by digital signal states (Low or High) of the linear feedback shift register (LFSR) based pseudo random binary sequence (PRBS) generator. The SVPWM offers a control degree of freedom in terms of positioning of vectors inside every sampling interval and hence it has six possible variants of the voltage vectors arrangements in each sector. The developed HSVPWM is thoroughly analyzed in using the MATLAB® based simulation for all SVPWM variants. From the simulation and experimental results viz. harmonic spectrum, harmonic spread factor (HSF), total harmonic distortion (THD) etc., and the superiority of the proposed scheme such as better utilization of DC bus and the randomization of the harmonic power are evidenced. For the practical implementation, Xilinx XC3S500E FPGA device has been used.

“…The inverters in the literature can be divided into two main categories depending on the operation characteristic. The first group includes well-known and most commonly used traditional pulse width modulation (PWM)-type (Ursaru et al , 2009) and pulse amplitude modulation (PAM)-type (Tominaga et al , 1996) inverters. The basic operating procedure of PWM-type inverters is based on the conversion of direct voltage at the input to alternating voltage at the output with PWM modulation and appropriate switching sequence.…”

Purpose This paper aims to present the design and implementation of a new general-purpose single-phase buck-type inverter. Design/methodology/approach The operation of the proposed inverter is based on the general-purpose buck converter. The proposed buck-type inverter topology is designed with reduced numbers of passive and active elements to minimize design cost and complexity. Also, an efficient hybrid control technique based on the proportional‐integral‐derivative (PID) supported by open-loop control signal is offered for the control of the proposed inverter. The proposed hybrid control method improves the performance of the PID controller during the change of inverter operation parameters. A close to single-phase sine wave output voltage with low total harmonic distortion (THD) can be produced by the proposed inverter in a wide range of voltage and frequency lower than the inverter input voltage value. Findings Simulation and experimental test studies are applied to the proposed inverter. The experimental laboratory setup is built for 0–50 Hz, 0–100 Vp, 0.5 kW. Both the simulation and the experimental test results show that the single-phase inverter can produce close to sine wave output voltage with THD level under 5% in a wide range of frequency for various operating conditions and for different loads. Originality/value In this paper, a new topology and a new hybrid control technique that are patented by the corresponding author are implemented for a single-phase buck-type inverter through a scientific project. The operating results of the study reveal the efficient operating capability with a simple topology structure.

This paper presents a new triggering detection method of the Hardware Trojans in the combinational logic systems, using static hazard analysis. A malicious entity can introduce a Hardware Trojan (HT) into a design in order to denial of service, destroy or disable the system. Moreover, it could leak the confidential information and the secret keys before altered them. The Hardware Trojan (HT) threats should be analyzed with maximum importance through the entire lifecycle of the integrated circuit (ICs). A hardware protection against the detected harmful logic should also be implemented.
