Improving the large signal gain of dynamic linearizing modulator controlled boost converter

A traditional Boost Inverter generates output more than the applied DC-input. However, boost converter exhibits highly nonlinear control to output response. A Dynamic linearizing modulator (DLM) was used to control a boost converter which improves the large signal linearity of the converter at higher operating frequency. The DLM controlled boost converter has a conversion ratio which is highly dependent on the design of the modulator. These design limitations are described in this paper. Methods to overcome these limitations are proposed. Based on these proposals, an improved control strategy is validated using simulation and experiments.
