摘要:
In a watt-hour meter in which first and second input signals representing an analog electric current and an analog voltage of an alternating current are converted into first and second digital signals, a first adder produces a sum signal which represents a sum of the first input signal and an additional analog signal of a frequency different from that of the first input signal and which is substituted for the first input signal. The meter may further comprise a second adder which adds another additional analog signal to the second input signal. Alternatively, the meter comprises low-pass filters and oversample-and-convert circuits to produce the first and the second input digital signals. As a further alternative, the meter comprises a first inverter for inverting a selected one of the first and the second input signals into a first inverted signal. In this event, a first selector alternatingly selects one of the first inverted signal and the selected one of the first and the second input signals and the other of the first inverted signal and the selected one of the first and the second input signals at a predetermined time interval as a first selected signal. A second inverter for inverting a product signal representing a product of the first and the second digital signals into a second inverted signal. Ganged with the first selector, a second selector alternatingly selects one of the second inverted signal and the product signal at the predetermined time interval as a second selected signal so that the second inverted signal is selected when the first selector selects the first inverted signal.
摘要:
Power source circuitry is disclosed and has a DC power source and a switching circuit positioned at the primary side, a diode and a coil positioned at the secondary side and serially connected to a load, and a capacitor connected in parallel to the load. A current bypass circuit is connected in parallel to the load, and operates when a voltage applied to the load momentarily increases. When a current flowing through a load sharply decreases, the current bypass circuit conducts an abnormal current to be input to the load to the negative side. This suppresses the momentary increase in the voltage applied to the load. In a normal condition, no potential differences occur between the base and the emitter of a transistor, so that the transistor remains in an OFF state and prevents a current from flowing through the bypass circuit.
