Voltage conversion apparatus, power output apparatus, and control method of voltage converter

摘要

An upper limit value setting unit (52) of a control device (30) conducts integration on the change in battery power (Pb), and determines whether the integrated value is lower than a preset first threshold value (A) (negative value) (step S30). When determination is made that the integrated value is lower than the first threshold value (A), and the battery power difference is lower than the second threshold value (”P kW) (negative value) (step S40), the upper limit value setting unit (52) sets Vup2 that is lower than the general Vup1 as the upper limit value of the inverter input voltage command (step S50).
