  • Publication number: 20170169140
    Abstract: A simulation test system of a cluster-based microgrid integrated with energy storages is characterized in that an operation simulation test of a physical microgrid system is conducted with a computer as well as a power generation data and a power consumption data which are imported. Hence, the user can verify the feasibility of applying various design concepts and ideas, such as controller parameter design and system energy management strategies, to a physical microgrid system, without installing or using any physical apparatuses.

  • Patent number: 9049763
    Abstract: The present invention relates to an LED luminaire driving circuit with high power factor, comprising: a filter unit, a rectifier unit, a transformer unit, a power switch unit, a zero current detecting unit, a feedback unit, an error amplifier unit, and a power switch driving unit. Particularly, the LED luminaire driving circuit proposed by the present invention does not include any optocoupler feedback circuits, so it is able to effectively reduce the entire circuit manufacturing cost of this LED luminaire driving circuit. Moreover, this LED luminaire driving circuit can selectively work under CCM operation or DCM operation with high power factor (PF˜1), and provide stable output voltage signal and output current signal to load end. In addition, this LED luminaire driving circuit performs excellent stability and current modulation error rate (<±3%).

  • Patent number: 8929109
    Abstract: The present invention relates to a double-output half-bridge LLC serial resonant converter, comprising: a half-bridge rectifying unit, a first resonant unit, a first transformer unit, a first rectifying unit, a first output unit, a second resonant unit, a second transformer unit, a second rectifying unit, a second output unit, a voltage dividing unit, a voltage regulating unit, a light-coupling isolation unit, and a control unit. In the present invention, the double-output half-bridge LLC serial resonant converter has an inventive circuit framework, which can not only solve the unbalance load current and the output voltage cross regulation occurred in the conventional double-output convertor, but also normally modulate the no-load or light-load output voltage; therefore the output voltage deviation can be effectively controlled.

  • Patent number: 8786215
    Abstract: The present invention relates to a double-output high-efficiency LED light-modulating circuit, comprising: a single-stage flyback power factor corrector, a DC/DC convertor, an LED module, and a light-modulating switch. In the present invention, it mainly utilizes the single-stage flyback power factor corrector for carrying out the purposes of reducing the components of an LED luminaire controlling circuit and increasing the circuit power conversion efficiency. Moreover, the double-output high-efficiency LED light-modulating circuit further includes a twin-bus light modulation framework, which can not only reduce the cross voltage of the power switch in back-end DC/DC convertor, but also process a high-frequency light modulation and a low-frequency light modulation to the LED luminaire. Therefore, because the cross voltage of the power switch has been reduced, a power switch with lower Rds can be used in the back-end DC/DC convertor for increasing switching speed and reducing switching losses.
