Publication number: 20210273570Abstract: A power converter system includes an input rectifier configured to rectify a line power having a line energy and a full-bridge isolating converter comprising a transformer, where the full-bridge isolating converter is configured to generate an isolated output voltage based on the rectified line power, and where the isolated output voltage is electrically isolated from the line energy. The power converter system includes a power controller configured to operate the full-bridge isolating converter to generate the isolated output voltage, determine whether the transformer is operating in a flux walk state based on an electric current of the transformer, and perform a corrective action in response to the transformer operating in the flux walk state.Type: ApplicationFiled: May 18, 2021Publication date: September 2, 2021Applicant: WATLOW ELECTRIC MANUFACTURING COMPANYInventors: Keith NESS, Geoffrey ROZEK, Stanton H. BREITLOW, James HENTGES, John LEMKE, William BOHLINGER, Matthew YENDER

Patent number: 10908196Abstract: The present disclosure is directed toward a control system for controlling a heater that includes at least one heating element. The control system includes a power converter operable to supply an adjustable voltage output to the heater, a sensor circuit that measures an electrical characteristic of the heating element of the heater, a reference temperature sensor that measures a reference temperature of a reference at the heater, and a controller. The controller is configured to calculate a primary temperature of a heater element based on the electrical characteristic and determines the voltage output to be applied to the heater based on at least one of the reference temperature and the primary temperature. The controller is configured to operate in at least one of an operation mode and a learn mode, and execute protection protocols when voltage is being supplied to the heater.Type: GrantFiled: May 2, 2019Date of Patent: February 2, 2021Assignee: Watlow Electric Manufacturing CompanyInventors: Stanton Hopkins Breitlow, James Hentges, William Bohlinger, Matthew Yender, Keith Ness, Kurt Peterson, Eric Meech, Brittany Phillips, Larry Walters, Geoffrey Rozek

Patent number: 10908195Abstract: A control system for controlling a heater includes a power converter, a sensor circuit, and a controller. The power converter supplies an adjustable power to the heater, and the sensor circuit is configured to measure an electrical characteristic of the heater. The controller is coupled to the power converter to control the power to the heater, and is configured to select a state model control, as an operation state of the heater, from among a plurality of defined state model controls. The controller controls the power supplied to the heater based on the operation state of the heater and on the electrical characteristics of the heater.Type: GrantFiled: August 10, 2018Date of Patent: February 2, 2021Assignee: Watlow Electric Manufacturing CompanyInventors: Stanton Hopkins Breitlow, James Hentges, William Bohlinger, Matthew Yender, Keith Ness, Kurt Peterson, Eric Meech, Brittany Phillips, Larry Walters, Geoffrey Rozek
