Free QuoteEach boost converter is evaluated on its capability to operate efficient, size, and cost of implementation. Conventional boost converter and interleaved boost converter are widely used topologies in photovoltaic systems reported; however, they have negative sides of varied efficiency level under changed weather conditions.
Since capacitor value directly depends on the maximum power, most of the inverters use electrolytic capacitors parallel to the PV module. This element reduces the lifetime and increases the cost of the photovoltaic system , . Thus, the solar PV inverter desires to use reduced capacitance value.
Abstract: The output voltage of a photovoltaic panel is greatly affected by irradiance, temperature, shading, etc. A buck-boost type inverter is, therefore, required to accommodate the wide fluctuations in dc voltage.
Another important requirement of the inverter is to protect against overload conditions. Therefore, when designing a system, the power rating of the inverter should normally be greater than 90% of the maximum power of the PV module, .
This element reduces the lifetime and increases the cost of the photovoltaic system, . Thus, the solar PV inverter desires to use reduced capacitance value. Boost inverter uses dc link inductors to maintain a constant current, thus less capacitance value is used in dc link.
Grid-connected solar PV systems require a rapid and proper control technique to switch the inverter. Commonly used control techniques are current control and voltage control techniques.
