High Voltage Solar Controller For Hvdc Pv Transmission System & Applications With Closed Loop Mppt Control
The talk of the world today is extracting energy from the renewable resources of energy. The difficulty arises when it comes to Transmission of HVDC generated from Solar Energy. The conventional converters aren’t suitable for HVDC Transmission system in which Solar PV is used as a source of energy. HVDC Transmission system involves usage of MMCs (Modular Multi-level converter), which require generation of AC Voltage as it converts High voltage AC to High Voltage DC, thus it lacks the flexibility to operate with Solar PV source.
Thus, a Boost Converter is designed for HVDC Transmission system with Solar PV as source and also for Solar PV Applications yielding High Efficacy. This converter has closed loop control to maintain constant output voltage and uses MPPT Algorithm for high efficiency. Also, for High Boosting with low duty cycle, the converter uses two cascaded Voltage Multiplier cells along with a Single-switched Boost Converter.
