ABSTRACT

• Various kinds of differential power processing
  converters and voltage equalizers have been
  proposed for series connected photovoltaic
  (PV)modules to prevent negative influences of
  partial shading,
• such as significant reduction in power generation
  and the occurrence of multiple maximum power
  points (MPPs), including local and global MPPs,
  that hinders and confuses MPP tracking algorithms
  to operate properly.
• However, since conventional topologies are based
  on multiple individual dcdc converters, the
  required switch count increases proportionally to
  the number of modules connected in series,
  increasing the complexity.
• A two-switch voltage equalizer using an LLC
  resonant inverter and voltage multiplier is
  proposed in this paper.
• The circuitry can be dramatically simplified
  compared with conventional topologies due to the
  two-switch configuration.
• Detailed operation analyses for the LLC resonant
  inverter and voltage multiplier are separately
  performed.
