“…However, as increases, the SPWM performance rapidly degrades, while the remaining CPWM methods maintain low HDF over a fairly wide range. The THIPWM method with the theoretically minimum HDF (THIPWM1/4 with ) [8] has only slightly smaller HDF than SVPWM and the conventional THIPWM (THIPWM1/6 with ). Since SVPWM is easier to implement and has a wider voltage linearity range, it is superior to all CPWM methods [10].…”

“…Given an HDF limit, the transition point can be easily determined from Fig. 14. More precise calculations to determine its value could involve (8) and (15) [10]. 2) Constant inverter average switching frequency -In this case, the carrier frequency for the SVPWM case is selected as and for GDPWM as , such that the inverter average switching frequency remains constant.…”

“…Thus, King's method, also termed the space-vector PWM (SVPWM) method, significantly improves inverter voltage utilization. The following years witnessed the development of several similar modulation methods, such as the third harmonic injection PWM (THIPWM) method [5], [7], [8]. Utilizing a discontinuous type of zero-sequence signal, Depenbrock developed a modulation method with discontinuous modulation waves (later named as the discontinuous PWM (DPWM) method and hereinafter referred to as DPWM1) that also provides a wider linearity range than SPWM [9].…”

Abstract-In this paper, a generalized discontinuous pulsewidth modulation (GDPWM) method with superior high modulation operating range performance characteristics is developed. An algorithm which employs the conventional space-vector PWM method in the low modulation range, and the GDPWM method in the high modulation range, is established. As a result, the current waveform quality, switching losses, voltage linearity range, and the overmodulation region performance of a PWM voltage-source inverter (PWM-VSI) drive are on-line optimized, as opposed to conventional modulators with fixed characteristics. Due to its compactness, simplicity, and superior performance, the algorithm is suitable for most high-performance PWM-VSI drive applications. This paper provides detailed performance analysis of the method and compares it to the other methods. The experimental results verify the superiority of this algorithm to the conventional PWM methods.

“…More recently, a switching strategy proposed, referred to as "regular sampling", is considered to have a number of advantages when implemented digitally. They are immune to noise and are less susceptible to voltage and temperature changes, hence, the digital implementation [3][4][5][6] . Generation of PWM gating signals requires a high sampling rate, for wide-bandwidth performance.…”

Problem statement:The design and implementation of a sinusoidal Pulse-Width Modulation (PWM) generator for a single-phase hybrid power filter is presented. Approach: The PWM was developed in an Altera® Flex 10 K Field Programmable Gate Array (FPGA) and the modulation index was selected by calculating the DC bus voltage of the active filter through a digital controller, by Proportional-Integral-Derivative (PID) technique. Results: Experiment results showed the proposed active power filter topology to be capable of compensating the load current and the voltage harmonic, up to IEC limit. Conclusion: The implemented PWM generator using an FPGA required less memory usage while providing flexible PWM patterns whether same phase, lagging, or leading, the reference voltage signal.
