Sinusoidal Pulse Width Modulation

This paper presents simulation and experimental verification of a single stage DC to AC boost inverter for solar photovoltaic (SPV) applications. This topology integrates the boost converter inside the conventional h-bridge inverter topology. This eliminates the need for a separate boost converter. The whole system requires four basic switches of an h-bridge inverter for both boost and DC-AC conversion operation. Overall, the efficiency is improved because no additional switch is required for the boosting operation. The duty cycle variations are implemented using sinusoidal pulse width modulation (SPWM). The firing pulses for switches used in the h-bridge inverter are provided using Arduino-Uno platform. The principle of operation along with the simulation and experimental results are also presented.

Sonic Environment

The 1-bit sonic environment (perhaps most famously musically employed on the ZX Spectrum) is defined by extreme limitation. Yet, belying these restrictions, there is a surprisingly expressive instrumental versatility. This article explores the theory behind the primary, idiosyncratically 1-bit techniques available to the composer-programmer, those that are essential when designing “instruments” in 1-bit environments. These techniques include pulse width modulation for timbral manipulation and means of generating virtual polyphony in software, such as the pin pulse and pulse interleaving techniques. These methodologies are considered in respect to their compositional implications and instrumental applications.
