Engine generator
Document Type and Number:
Japanese Patent JP6193681
Kind Code:
B2
Abstract:
An engine generator detects a DC voltage in a path from a rectifier to an inverter in controlling charge/discharge, and makes a duty ratio in switching control of a charging conductor of a power storage device higher than a duty ratio in the switching control of a discharging conductor of the power storage device when the DC voltage is higher than a target voltage of the DC voltage, and makes the duty ratio in the switching control of the discharging conductor of the power storage device higher than the duty ratio in the switching control of the charging conductor of the power storage device when the DC voltage is lower than the target voltage.
