“…The diagram of the current hysteresis controlled PWM is given in Figure 12A. 48,49 In order to understand the hysteresis controlled PWM a single phase inverter with RLE load is taken. When the upper switch of the single phase inverter is ON the current starts increasing and when the currents hits the upper band ðI V Þ in order to decrease the current the lower switch of the inverter is turned on.…”

Use of Pulse Width Modulation (PWM) techniques has enabled the converters to be used in low-frequency high-power applications. The main objectives of PWM are to reduce the line current harmonic, switching energy loss, and torque pulsation and motor acoustic noise (for motor drive applications). This paper mainly deals with selective harmonic elimination PWM (SHEPWM), Hysteresis current controlled PWM (HCPWM), space vector PWM (SVPWM), bus-clamping PWM (BCPWM), and the most advanced wavelet PWM technique (WPWM). Different conventional as well as advanced soft computing

In this paper, a new control strategy for an induction motor (IM) drive system fed from three-phase pulse width modulation (PWM) ac chopper is proposed. The main objective of the proposed control scheme is to achieve input power factor correction (PFC) of the IM drive system under different operating conditions. PFC is achieved by continuously forcing the actual three-phase supply currents with the corresponding reference currents, which are generated in phase with the supply voltages, using hysteresis band current control (HBCC) technique. The proposed control strategy has two loops: the inner loop and outer loop. The output of the outer loop is the magnitude of the supply reference current resulting from either speed controller or startup controller, whereas the output of the inner loop is PWM signals of the ac chopper. The proposed ac chopper features a smaller number of active semiconductor switches, four IGBTs, with only two PWM gate signals. As a result, the proposed system is simple, reliable, highly efficient, and cost effective. Mathematical analysis of the drive system is presented. Components of the input LC filter are designed using frequency response. The IM drive system is modeled using MATLAB/SIMULINK, and a laboratory prototype was built and tested. The simulation and experimental results confirm the validity and robustness of the proposed control strategy. INDEX TERMS Hysteresis band current control, induction motor drive, power factor correction, pulse width modulation, three-phase AC chopper.

Reducing the number of active switches is substantial for obtaining a simple, reliable, highefficiency, and cost-effective AC/AC voltage converter. In this paper, two topologies of three-phase direct PWM AC/AC voltage converter are proposed. The first is for the buck converter and the other is for the boost one. Each converter has no DC energy storage elements and employs only three IGBTs. The proposed converters do not use lossy snubber circuits and have not commutation problems. A simple, reliable, and cost-effective control strategy, which employs only one voltage sensor, is also proposed. Using a closedloop voltage control technique, two complementary PWM gate signals are generated to drive the three active switches of each converter. Adjusting the duty ratio of PWM gate signals regulates the output voltage of the AC/AC converters. Operating principle and mathematical analysis of the converters are presented. Voltage stresses across active and passive semiconductor switches of the proposed converters are derived. Small signal analysis based on complex DQ transformed equivalent circuits of the converter is introduced. Voltage controller design using frequency response analysis is provided. The converters are simulated using MATLAB/SIMULINK and laboratory prototypes are implemented in real-time using DSP-DS1104 control board. The converters are tested under different operating conditions and their performances are investigated and compared. The symmetry of the output voltage/current is examined by the theory of symmetrical components. The simulation and experimental results are in a close agreement. This confirms the validity of the theoretical analysis, the effectiveness of the control strategy, and the feasibility of the proposed converters.INDEX TERMS AC-AC voltage converters, control design, small signal analysis, stability analysis, symmetrical components, voltage stress.
