Description

SOLAR MPPT  CHARGER 30A TO 100A

 The power delivered by solar panels depend upon the current drawn, environmental conditions

like temperature, solar radiation etc. Maximum Power Point Tracking (MPPT) is a method of

extracting maximum available power from Solar Panel to load, batteries or devices like inverters, etc…

MPPT action in UNIVERSAL two phase interleaved MPPT solar charger is done by shifted phase modulation in interleaved switching. The DSP will vary PWM duty cycle of interleave switching for obtaining the Maximum Power Point. The DSP will continuously multiply voltage and current from the panel while varying the duty cycle of interleave switching. At a particular duty cycle the maximum wattage (V x I) is obtained. The DSP will track this point continuously and ensures the working of MPPT Charger is always at this Maximum Power Point. Since it is two phase interleave switching, the Maximum Power Point Tracking will be more efficient than the conventional switching MPPT chargers. The circuit is based on DSP. The DSP will intelligently calculate at what impedance the maximum power is transferred from the panel to the battery. The DSP will scan the impedance (i.e. transformation ratio between the panel and battery) of the circuit from maximum to minimum and find out at which point the maximum power is delivered. Then the DSP fixes the impedance at that point
