Summary, etc <br/>There are several converters where input stage is AC-DC rectification. Rectifiers are nonlinearload and for their operation, they draw pulsating input current from AC mains and thus pollutesthe utility grid by injecting harmonics which results in poor power factor. To improve powerfactor, power factor correction circuits can be used. Powerfactor correction (PFC) circuits can becategorized into two types 1.) Passive power factor correction, 2.) Active power factor correction.Application of passive PFC converter is limited to low powerdue to the increased size of filtercomponents and lack of output voltage control. Active PFC can alleviate the issues related withpassive PFC by replacing passive elements with controlled solid state switches. PFC rectifier canuse several DC-DC converter topologies such as boost, buck,flyback, bridgeless and interleaved.One of the widely used topology is PFC boost rectifier becauseof its step up characteristics,simplicity, efficiency and performance. In bridgeless PFC rectifier, the absence of an input diodebridge and the presence of only two semiconductor devices inthe current flowing path during eachinterval of the switching cycle result in less conduction losses and an improved thermal managementcompared to the conventional PFC rectifier. For this thesis work active bridgeless Power FactorCorrection with dual boost rectifier is presented along withsuitable switching control. Controlcircuit for bridgeless Power Factor Correction with dual bridge boost rectifier is designed usingIntegral Sliding Mode (ISM) controller integrated with proportional plus integral plus derivative(PID) controller. Integral Sliding Mode (ISM) allows combining two different type of controllerwithout complete redesign, i.e. for a nominal converter model PI controller may have desiredperformance, however, by combining with ISM, the converterdemonstrates additional robustnessproperty. Use of Integral Sliding Mode controller eliminated the matched disturbances which whichimproved input current waveform to approximately sinusoidal waveform and power factor is alsoattained close to unity with low total harmonic distortion.<br/>
