During a power outage, the battery DC voltage is boosted to 330V DC via a high-frequency transformer and MOSFETs (push-pull topology). This high voltage is then chopped by a full H-bridge (using MOSFETs like IRF740 or K3568) to produce a modified sine wave (or pure sine wave in premium models) at 220V/50Hz.
