Patent number: 10480840Abstract: Systems and methods for providing power to a refrigeration unit or an air conditioner used on a hybrid vehicle. The system includes an accumulation choke, a PWM rectifier, and a frequency inverter. The accumulation choke is configured to receive a first AC power, a second AC power, and a DC power. The accumulation choke and PWM rectifier convert the received power into an intermediate DC power having a peak voltage. The PWM rectifier provides the intermediate DC power to the frequency inverter. The frequency inverter converts the intermediate DC power to an output AC power. The frequency inverter provides the output AC power to the refrigeration unit.Type: GrantFiled: June 19, 2017Date of Patent: November 19, 2019Assignee: Thermo King CorporationInventors: Gregory R. Truckenbrod, Arnost Hurych, Bruce H. Kranz, Eric Kirby, Michael D. Gilman, Richard W. Schmidt

Patent number: 9764616Abstract: A HVAC system for a vehicle that includes a propulsion system, a frame, a passenger compartment, and a door coupled to the frame. The HVAC system includes a refrigeration circuit that selectively controls the temperature of the passenger compartment based on a sensed temperature within the passenger compartment. The refrigeration circuit includes an exterior heat exchanger, a first air moving device coupled to the exterior heat exchanger, an interior heat exchanger, a second air moving device coupled to the interior heat exchanger, and a compressor. The HVAC system also includes a controller that is operable to detect a condition of the vehicle that includes at least one of a position of the door, a location of the vehicle, and a load of the propulsion system. The controller is programmed to adjust the refrigeration circuit in response to the sensed passenger compartment temperature and the detected vehicle condition.Type: GrantFiled: June 2, 2015Date of Patent: September 19, 2017Assignee: THERMO KING CORPORATIONInventors: Michal Hegar, Arnost Hurych, Michal Kolda, Antonin Ryska

Patent number: 8605472Abstract: A buck/boost rectifier. The rectifier is connectable to an alternating current power source and includes an upper bus, a lower bus, an upper rectifier, a lower rectifier, a pulse-width-modulation (PWM) controller, a phase-angle (PA) controller, and a capacitor. The upper rectifier is coupled to the upper bus, and the lower rectifier is coupled in a series-type relationship with the upper rectifier and to the lower bus. The PWM controller is coupled to the lower rectifier and is configured to boost a direct current (DC) voltage output by the rectifier. The PA controller is coupled to the lower rectifier and is configured to buck the DC voltage output by the rectifier. The capacitor is coupled between the upper bus and the lower bus.Type: GrantFiled: October 12, 2011Date of Patent: December 10, 2013Assignee: Thermo King CorporationInventors: Arnost Hurych, Vladimir Kmoch
