This article studies on a design and Verification of classical controllers (CC) for Transformer less DC-DC Boost Converter (TDC-DCBC) operated in Continuous Conduction Mode (CCM) for applications wanting a stable power source in I-pad, mobile phones, MP-3 player, lap-top computers, robot interface communication device and solar energy etc.,.  Attributable to the ON/OFF characteristics of TDC-DCBC is non-linear in nature and it generates meager dynamic performances and also, unsatisfactory output voltage regulation. With the aim of increase the dynamic performance and output voltage regulation of TDC-DCBC, a CC is designed. In this article proportional integral (PI) controller is taken as one of the CC. The PI controller parameters are arrived from the modeling of TDC-DCBC with help of the state space averaging approach. The performance of the designed converter with PI controller is validated at different operating state by building both matrix laboratory (MATLAB)/simulation link (Simulink). The results are presented to prove the performance designed converter with CC.
