This paper deals with the modeling and simulation of low voltage power supply (LVPS) unit to the ACTIVE PHASED ARRAY RADAR, which is used for sensing different targets at a time. This RADAR system contains flat bank of small identical antennas and huge number of transmitting and receiving modules for electronic scanning. This radar antenna requires power in different levels for various electronic devices. The proposed design of LV power supply will have the ability to manage temperature variations with high efficiency under different loading condition. The closed loop control such as voltage mode control and current mode control are used to regulate the output voltage with high switching frequency of 400khz has been designed. Simulations are performed using MATLAB / SIMULINK software.
