Latest Patents

Hui Zhang holds a patent for a Neutral-point-clamped multilevel power conversion device. This invention provides a power conversion device in which an on-pulse bias voltage and a neutral-point bias voltage do not interfere with each other. The device features a polarity judgment section that assesses the polarity of a neutral-point bias voltage calculated by a neutral-point potential fluctuation suppression control section of a voltage command value control circuit. Based on this polarity, the device selects a polarity of an on-pulse bias voltage through an on-pulse control section. This innovative control mechanism prevents the polarities of the neutral-point bias voltage and the on-pulse bias voltage from differing, thereby avoiding interference between the two bias voltages.
