Description
We use a standard DC-to-DC power converter of the ‘boost’ type to automatically generate a desired AC output capacitor voltage signal using sliding mode control. We use an off-line iterative algorithm, which is based on the differential flatness of the traditional boost converter circuit, and results in a suitable sliding surface candidate for on-line feedback control purposes. Based on inductor current measurements, the sliding surface candidate is synthesized which guarantees an approximate sinusoidal output voltage waveform to the desired reference signal. The actual sliding mode controller implementation used a DSP TMS320C31, which exhibits large processing speed and floating-point capabilities, necessary to achieve the required arithmetic precision. For the A/D conversion we used the TLC32040 with a suitably high conversion rate.
