The power conversion circuit includes an inverter with a first stage electrically coupled to one or more solar panels. A third stage of the circuit has a DC to AC converter that provides less than a 50 VAC load voltage to a load, and a second stage that is coupled between the first and third stages and provides an isolated electrical power coupling therebetween. A sync interface communicatively couples a controller to other controllers dedicated to one or more other respective inverters of the solar array via a sync signal. The controllers synchronize the third stages of the inverters via the sync signal. The third stages of the inverters are coupled in series to provide a load output voltage.Type: GrantFiled: June 7, 2022Date of Patent: May 14, 2024Assignee: NDSU Research FoundationInventors: Mijia Yang, Dong Cao, Yao Yu

Patent number: 9322852Abstract: Gate drive faults are detected for an inverter which comprises a phase switch having an insulated gate, such as an IGBT. A complementary transistor pair is adapted to receive a supply voltage and a pulse-width modulated (PWM) signal to alternately charge and discharge the insulated gate. A comparator compares the voltage at the insulated gate with a reference voltage representing a gate drive fault to generate a first logic signal. A latch samples the first logic signal when the PWM signal has a value corresponding to charging the insulated gate. A logic circuit inhibits charging of the insulated gate when the latched logic signal indicates the gate drive fault. An insulated gate voltage less than the reference voltage is indicative of an under-voltage fault as well as other device failures of the IGBT or the complementary transistors.Type: GrantFiled: July 15, 2014Date of Patent: April 26, 2016Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Lihua Chen, Dong Cao, Yan Zhou, Craig Rogers

Patent number: 8954579Abstract: Embodiments are directed to verifying the accessibility and functionality of an online service and to scheduling the automatic execution of an online service. In one scenario, a computer system receives online service workflows and corresponding expected outcomes for each workflow. Each online service workflow is associated with an online service, and each online service workflow includes workflow steps that cause the online service to perform specified operations that produce observable outcomes within a specified amount of time specified by the online service provider. The computer system executes at least one of the received online service workflows and abandons execution of the online service workflow if execution is not completed within the specified amount of time. The computer system also compares the outcomes of the workflow execution to the expected outcomes corresponding to the executed online service workflow and generates a report that includes the results of the comparison.Type: GrantFiled: August 21, 2012Date of Patent: February 10, 2015Assignee: Microsoft CorporationInventors: Minh Quang Anh Do, Dong Cao, Mahesh Dudgikar
