Patent number: 11588373Abstract: A kinetic energy recovery system with flywheel includes a cascade flywheel doubly-fed electric machine and an electric motor. The cascade flywheel doubly-fed electric machine has a stator end coil, a rotor end coil and a flywheel. The flywheel can store kinetic energy by increasing speed or releasing kinetic energy by decreasing speed. A control circuit has an inverter, a rectifier and a DC bus connecting the inverter and the rectifier. The inverter supplies alternating current to the rotor end coil. The rectifier has an AC end connected to the stator end coil through an AC bus. The rectifier converts alternating current to direct current, so that the inverter can draw power from the DC bus. The electric motor has a phase coil connected to the AC bus. When the cascade flywheel double-fed electric machine decelerates, the system converts mechanical energy into electrical energy.Type: GrantFiled: July 13, 2020Date of Patent: February 21, 2023Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Ming-Tsan Peng, Chia-Lin Wu, Huan-Lung Gu, Chih-Wei Yeh

Publication number: 20220346199Abstract: A microwave heating method and a microwave heating device are provided. The microwave heating method includes the following steps. An electric field mode distribution at each frequency point generated by the microwave outputted from each input port of the heating chamber is calculated. A frequency, phase, and power of the microwave outputted from each input port are changed to generate a corresponding electric field mode distribution. The electric field mode distributions generated by the input ports are synthesized into a synthesized electric field mode distribution. A power density distribution is calculated. It is calculated whether spatial uniformity of the power density distribution is greater than a target value. The controller heats the object to be heated through the microwave corresponding to the frequency, phase, and power emitted by the microwave transmitter corresponding to each input port.Type: ApplicationFiled: December 15, 2021Publication date: October 27, 2022Applicant: Industrial Technology Research InstituteInventors: Kun-Ping Huang, Joseph Poujiong Wang, Ming-Tsan Peng

Patent number: 10985564Abstract: An electric power-regulating system includes an electric-load end, a power-supply end, a power regulator, a DC-bus device, a flywheel energy-storage device, a switch device and a controller. The flywheel energy-storage device connects the DC-bus device. The switch device is connected between the flywheel energy-storage device and the DC-bus device. The switch device provides at least one current-flow direction between the DC-bus device and the flywheel energy-storage device.

Patent number: 8547712Abstract: A power circuit is applicable to a Direct Current (DC) to DC converter. The power circuit includes a gate driver circuit and a High Electron Mobility Transistor (HEMT). The gate driver circuit functions as a Sigmoid (S) function and controls a gate and a source of the HEMT with a cross voltage of the sigmoid (S) type function. Accordingly, an overall characteristic curve of the HEMT and the gate driver circuit is like a characteristic curve of a single rectifier diode, so as to achieve a rectifying, freewheeling, or reversing effect. In addition, since an energy loss is low when the HEMT is conducted, the energy loss of the whole power circuit is much less than that of a conventional diode.Type: GrantFiled: January 26, 2011Date of Patent: October 1, 2013Assignee: Industrial Technology Research InstituteInventors: Edward-Yi Chang, Shyr-Long Jeng, Ming-Tsan Peng
