Abstract: Disclosed are a power conversion apparatus and a photovoltaic module. The power conversion apparatus includes a converter unit configured to convert a direct current (DC) voltage from a solar cell module, a clamp unit configured to limit a surge voltage in the converter unit, and a controller configured to control the converter unit. Through this configuration, the power conversion apparatus is capable of limiting a surge voltage depending on operation of the converter unit.
