The High-Frequency Inverter is mainly used today in uninterruptible power supply systems, AC motor drives, induction heating and renewable energy source systems. The simplest form of an inverter is the bridge-type, where a power bridge is controlled according to the sinusoidal pulse-width modulation (SPWM) principle and the resulting SPWM wave is filtered to produce the alternating output voltage.

A stack overflow in an embedded DSP application generally produces a catastrophic software crash due to data corruption, lost return addresses, or both. Traditional off-line approaches to sizing a stack during development, such as filling with a know value, or estimating based on code content, are not 100% reliable. Therefore, programmers often feel compelled to reserve larger stack sizes than are
