The efficiency of thermoelectric generators (TEGs) is quite low. To operate the TEGs at maximum power point (MPP), internal resistance connected load and TEG must be equal. This not always possible. For this, converters containing tracking (MPPT) algorithm MPP are placed between load. These cannot perform MPPT on every value. aim this study to investigate which values can performed in non-isolated boost by using perturb & observation (P&O) method. purpose, a 50 W converter was...
