Indian Patent Applicaton No: 

918/DEL/2013

Date Filed: 

26.03.2013

Overview: 

Controlling method of an inter-connected utility system based on photovoltaic sources, which is implemented through analog electronics

Key Features: 

  • The Control apparatus is used for tracking a maximum power point (MPP] for a solar photovoltaic panel
  • Control apparatus is based on-line computation of maximum terminal voltage (Vpmax) of the SPV panel.
  • It has an insignificant perturbation in the SPV-panel voltage is applied and change in power is tracked.
  • An analog MPPT controller which attains MPP without using multiplier and storage elements.
  • The proposed controller operates under the principle of Voltage perturbation

Applications: 

  • Energy productivity.
  • Power tracking solar power system.
