摘要： The invention relates to an apparatus and method for tracking energy consumption. An energy tracking system comprises at least one switching element, at least one inductor and a control block to keep the output voltage at a pre-selected level. The switching elements are configured to apply the source of energy to the inductors. The control block compares the output voltage of the energy tracking system to a reference value and controls the switching of the switched elements in order to transfer energy for the primary voltage into a secondary voltage at the output of the energy tracking system. The electronic device further comprises an ON-time and OFF-time generator and an accumulator wherein the control block is coupled to receive a signal from the ON-time and OFF-time generator and generates switching signals for the at least one switching element in the form of ON-time pulses with a constant width ON-time.

摘要： A process variable such as the load current supplied through an electrical contactor is encoded as a 4 to 20 mA current signal via an optically coupled pulse width modulated output circuit. A microprocessor produces the pulse width modulated signal at a duty cycle varying with the load current. The LED of an opto-coupler transfers the signal to a phototransistor, and a voltage regulator and switching circuit drive the phototransistor so as to minimize switching times. The voltage regulator maintains a DC voltage at the collector of the phototransistor, which is operated at a constant emitter current. The LED supplies base current to the phototransistor when the pulse width modulated signal is high. An amplifier is coupled to the emitter of the phototransistor, and the output of the amplifier is coupled back to the base of the phototransistor via a Schottky diode pair. The amplifier output varies with whether or not the base current needed to maintain constant emitter current is obtained from the LED. The amplifier output is coupled via a comparator and a low pass filter to a current driver including an amplifier and a drive transistor. The DC component of the current output varies with a duty cycle of the pulse width modulated signal, providing a 4 to 20 mA output current with variation of the load current between zero and 200% of rated load current.

摘要： A time of use register for use in an electronic watthour meter is formed of a three piece interlocking construction without the use of separate fasteners or the use of tools for assembly. The TOU register includes a front cover, a rear cover and a resilient clip, each of these components having various features to provide firm containment of a PC board and an LCD within the register. The front cover includes a window within which the LCD is positioned and a connector slot within which a resilient electrical conductor strip is situated. The electrical conductor strip provides communication between the PC board, which has a contact array at one edge of the board, and the LCD array, which also has a complementary contact array at its upper edge. The rear cover encloses the rear and part of the sides of the TOU register and includes a number of stops for providing uniform pressure against the PC board to hold it in position. The front and rear covers include a number of catches upon which the resilient clip, and particularly a number of notches on the resilient clip, is snapped. When the resilient clip is snapped onto the notches of the front and rear covers, a specific amount of pressure is exerted against the components contained within the TOU register. The pressure is calibrated to provide a uniform compression of the resilient connector strip to insure a gas-tight electrical connection between the PC board and the LCD array.

摘要： A shift register is utilized to provide a 90.degree. delay in a pulse width modulated current signal to determine volt-amperes reactive. The shift register is associated with a clock that provides a preselected frequency that, in combination with the number of stages in the shift register, delays the pulse width modulated current signal by an amount equivalent to one-quarter period of the current waveform in the metered circuit. After delaying the pulse width modulated signal by 90.degree., the shifted signal is multiplied by a voltage signal that represents the voltage in the metered circuit and the resulting product signal is input to a voltage-to-frequency converter.
