Patent number: 10103647Abstract: A sensorless measurement device for filter capacitor current by using a state observer is provided. The sensorless measurement device comprises a chip, wherein the chip comprises the state observer. The state observer is configured to retrieve a filter-capacitor-voltage actual value and a direct current link (dc-link) voltage of a present sampling time. According to the filter-capacitor-voltage actual value and the dc-link voltage, the state observer is configured to output a filter-capacitor-voltage state variable value, a filter-capacitor-current state variable value, and a disturbance-voltage state variable value of a next sampling time. The filter-capacitor-current state variable value is an average current value without ripples.Type: GrantFiled: November 17, 2016Date of Patent: October 16, 2018Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Shu-Syuan Huang, Yoshihiro Konishi, Zong-Zhen Yang, Min-Ju Hsieh

Patent number: 8149603Abstract: The present disclosure relates to a resonance circuit for DC-link voltage control in a DC-to-AC inverter. The resonance circuit comprises two active switches. Before the active switches of the DC-to-AC inverter are turned on, a DC-link voltage is isolated by the active switches and the active switches of the DC-to-AC inverter are discharged by the resonance circuit to zero voltage at both ends. Then, the active switches of the DC-to-AC inverter are turned on again after the DC-link voltage is charged by the resonance circuit until the DC-link voltage restores to a normal voltage value. Hence, the active switches of the DC-to-AC inverter achieve zero-voltage switching. Not only the switching loss can be reduced to enhance the conversion efficiency, but also the electro-magnetic interference as well as the RF interference due to dynamic transient changes of the voltage (dv/dt) and of the current (di/dt) can be lowered.Type: GrantFiled: May 13, 2010Date of Patent: April 3, 2012Assignee: Industrial Technology Research InstituteInventors: Yung-Fu Huang, Yoshihiro Konishi, Min-Ju Hsieh
