Control of an alternating wave generator for voltage wave-shape and frequency

The requirements of generating various low frequency voltage waveshapes are usually catered by using linear amplifiers, which results in low overall efficiency. High frequency voltage source inverters with low pass filter at the output are not suitable for these applications, as it is difficult to produce waveshapes containing high frequency components, and variation in frequency. A Boost Inverter containing two boost converters, working to produce voltage waveshape of required specification but with 180° phase shift can produce such waveforms. This paper presents the operation, analysis, complete design and simulation result of such an inverter.
