In any type of power conversion basic requirement is converter. Converter is the heart of power electronics. All type of power
converter requires some special technique to control the converter. In this project some of this type converter and its control
strategy is designed and developed.In current scenario use of DC to DC converter is increased due to numerous advantages and
lots of applications. Efficiency and performance of the converter increased with latest control strategy. In this project one of the
control methods is design for dc to dc converter. Average power balance control (APBC) scheme is designed and analyzed for a
boost converter. The proposed scheme consists of two control loops, the fast inner current loop uses hysteresis current control
(HCC) and outer voltage loop uses the average power balance algorithm (APBA), which contains average power balance
equation (APBE) and PI controller.The existence condition of HCC is derived such that the stable tracking performance can be
ensured under occurrence of system uncertainties. The proposed APBC scheme is modeled and simulated using MATLAB /
SIMULINK. The effectiveness of APBC in terms of voltage tracking, transient response and robustness to uncertainties in
parameters are verified by simulation result.
