摘要： A refrigerated appliance that dispenses items includes a power source and a cooling system. Power control circuitry is electrically coupled between a power source (e.g., power cord coupled to a wall outlet) and components (for example, a compressor and one or more circulating fans of the cooling system) of the appliance. A controller, which is operably coupled to the power control circuitry, is adapted to manage the supply of electrical power to such components by intelligently transitioning between a normal-operation mode and at least one power-conserving mode. To achieve efficient power conservation, the controller automatically transitions between the at least one power-conserving mode and the normal-operation mode based upon at least one temperature signal, at least one dispensing event signal, and possibly other data signals supplied to the controller.

摘要： A refrigerated vending machine provides separate power conservation modes for the cooling system and the panel lights. Power conservation for the panel lights takes into account whether the vending machine is located indoors or outdoors. The location can be indicated by a setting by the vending machine operator or may be determined automatically according to maximum brightness or color temperature. If the vending machine is outdoors, the panel lights are turned off when the ambient is bright (to save energy when the panel lights are not needed) and turned on when the ambient is dark (to attract customers). If the vending machine is indoors, the panel lights are turned off when the ambient is dark (since the room is presumably vacant) and turned on when the ambient is bright (indicating the room is in use). Optionally, an occupancy sensor can be used to turn off the panel lights if the room light is on but no one has been detected in it. The cooling system uses a conservation mode in which circulation fans are switched off so only items in a position to be dispensed first or second are kept at the desired temperature.

摘要： A refrigerated soda vending machine includes sensors for monitoring various parameters such as temperature within its refrigerated chamber and for monitoring occupancy in the chamber vicinity. Sensor data is used to determine when to switch between normal and power-conservation modes of operation. In either mode, a cooling system is regulated so that a compressor goes on when an upper internal temperature threshold is reached and off when a lower internal temperature threshold is reached. In normal mode, fans circulate air to maintain a relatively uniform temperature throughout the chamber. During power-conservation mode, the fans are mostly off when the compressor is off. In the absence of circulation, the temperature within the refrigerated chamber stratifies so that a lower cool zone and an upper warm zone can be differentiated. Soda cans are held in vertical stacks so that the lowest cans are located in the cool zone.

摘要： An external power-management device controls the supply of electric power from a wall outlet to a refrigerated vending machine. The system includes a switch that couples power in an ON condition and decouples in an OFF condition. The switch is controlled by a controller based on data received from a current sensor, an occupancy sensor, a temperature sensor, and a time-of-year circuit. Upon startup, the current is monitored to determine maxima and minima for the vending machine. The system supplies power to the appliance during business hours as indicated by the time-of-year circuit and while the vicinity is occupied as determined by the occupancy sensor irrespective of the values for current and temperature. Absent the current sensor, the power would be decoupled after a predetermined duration of non-occupancy during nonbusiness hours. However, if the current sensor indicates a high (relative to the previously determined minima and maxima) current at the proposed shutdown time, shutdown is aborted to avoid interruption of a compression (cooling) cycle initiated by the vending machine. The temperature is used in determining when, after shutdown, power is resumed to permit vending machine contents to be cooled.

摘要： A method and circuit for reverse phase control of alternating current being delivered to a load are disclosed wherein voltage-controlled semiconductor switches, such as MOSFET's and IGBT's, are used as electronic switches to conduct voltage during the leading edge of the AC voltage cycle and conduction is terminated when the desired phase angle of the current flow has been reached. The disclosed method and circuit eliminate the need for zero crossing detection of the AC waveform and ensure that the voltage-controlled switches are always turned on before the zero crossing thereby minimizing radiated interference and incandescent lamp hum. The method used is primarily digital in nature making mechanical input or electronic input for the power control equally efficient to implement.

摘要： The present disclosure describes a circuit arrangement wherein a clock signal generator generates two sets of time-period, separated enable signals and wherein there is controllable first direction current flow circuitry and controllable second direction current flow circuitry. One set of said enable signals is connected to said first circuitry to cause current flow in a first direction during a first period of time while the other set of said enable signals is connected to said second circuitry to cause current flow in a second direction during a second period of time which is separated from said first period by a predetermined period. The arrangement insures that the circuitry will not attempt to drive current in both directions at the same time.

摘要： A spread-spectrum power converter uses an inter-cycle duty-cycle error compensation to achieve a combination of high-precision tracking of a target average duty cycle and a favorable noise signature. The pulse train consists of a series of cycles having cycle durations of a positive integer of clock cycles, pulse durations of a whole number of clock cycles, and duty cycles corresponding to a ratio of pulse durations over cycle durations. The pulse durations are selected at least in part as functions of a target average duty cycle, the respective cycle durations, and a ripple (or other) error from other cycles in the train. The cycle durations can also be in part a function of the target average duty cycle so that the duty cycle errors can be minimized.
