Abstract: Data is transmitted on a power line (15) as a momentary interruption of the power at or near the zero crossing of the current. The interruption is preferably a small fraction of the period of the frequency of the power line. The data is transmitted only to those devices in series circuit with the transmitter. The transmitter (13) combines 60 Hz and 120 Hz clock signals with data from a shift register to interrupt current in a predetermined pattern, in which an interruption of both the positive going and negative going zero crossings define a logic "1" and the absence of interruptions is a logic "0". A data prefix identifies succeeding bits as data. The receiver (17) produces a pulse width modulated signal in response to the data.

Abstract: A ballast circuit (100) includes a ground fault detector (200). The ballast circuit is arranged for coupling to a power source (101) and a load (135, 137), the power source characterized by a source frequency, the ballast circuit including an electromagnetic interference ("EMI") filter (110) which includes a ground terminal (145). The ground fault detector (200) determines when the load is coupled to a ground fault (141) by detecting the presence of a high-frequency current at the ground terminal, the high-frequency current characterized by a frequency that is substantially greater than the source frequency. When the high-frequency current is detected, the ground fault detector provides an output signal (150) which may be used to disconnect the load from the ballast circuit.

Abstract: A circuit (100) for powering fluorescent lamps (102, 104 and 106) includes a switch (50) having "open" and "closed" positions. When power is initially applied to the circuit, the lamps are powered at full power to enable them to "strike". After a short period, the power is reduced to the lamp. A control circuit (300) thereafter senses if the switch has been "toggled". If toggled, the power to the lamps is increased, and the lamps brighten. The circuit uses a conventional two-position switch and conventional wiring and avoids the need for additional switches and additional wiring.

Abstract: A circuit for dimmably driving fluorescent lamps (102, 104, 106) from a DC supply voltage includes: input nodes (174, 176) having input capacitors (184, 186) connected therebetween; a half-bridge transistor inverter (178, 180) connected between the input terminals; a series-resonant LC oscillator (196, 198) coupled in series between the half-bridge transistors and the input capacitors; an output transformer (212) having a primary winding (214) connected in series with the LC inductor (196) and in parallel with the LC capacitor (198) and a secondary winding (216) for connection to the lamp load; and first and second voltage clamp diodes (215A, 215B) connected between an intermediate point on the primary winding and the input nodes respectively. The voltage clamp diodes, in conjunction with the input capacitors, provide significant enhancement in reduction of power transferred to the lamps when the DC supply voltage is reduced, allowing lamp dimming to be simply and efficiently effected by reduction of the DC supply voltage.

Abstract: A ballast for providing a dimmable fluorescent lamp (42) has a potentiometer (46) connected to AC power source (10). The potentiometer (46) is connected to a dimming circuit (44). In response to changes in the resistance of the potentiometer (46), dimming circuit (44) causes the duty cycle of a pulse with modulator (18) to change, thereby dimming the fluorescent lamp (42). A dimming disable circuit (60) disables the dimming circuit (44) when power is initially applied to the ballast (6) so that the lamp (42) will ignite.

Abstract: A multi-resonant circuit has a series-resonant circuit (118) coupled to the input of an inverter (120). The output of the inverter is coupled to a parallel resonant circuit (108, 152). The output of the parallel resonant circuit energizes a load (142, 140), which could be gas discharge lamps.

Abstract: A circuit (100) for driving fluorescent lamps (102, 104, 106) and including: a half-bridge inverter (112) receiving a unidirectional voltage and producing an alternating voltage, and having control inputs (156, 166); a series-resonant oscillator (126) coupled to the inverter output (116) for producing an alternating signal; and a non-saturating feedback transformer (146) having a primary winding (148) coupled in series between the inverter and the oscillator and secondary winding (150, 152) coupled respectively to the control inputs of the inverter. Since the feedback transformer is non-saturating it provides to the inverter control inputs a linear feedback signal from the inverter. This results in safe, stable, predictable and well-defined circuit operation, in which the possibility of the inverter transistors being destroyed by cross-conduction is substantially removed, and the amount of input voltage ''ripple'' present in the signal applied to the lamps is reduced.

Abstract: A circuit for driving gas discharge lamps (102, 104, 106) having heatable filaments (102A&B, 104A&B, 106A&B) includes: a self-oscillating, series-resonant oscillator (196, 198, 178, 180) producing a high-frequency output voltage for application to the lamps; a resistive-capacitive divider (190, 192) for starting-up the oscillator after a first delay; an inductive voltage boost IC (144) for causing the oscillator to produce a boosted output voltage when the voltage boost IC is activated and an unboosted output voltage when unactivated; and a resistive-capacitive divider (170, 172) for starting-up the voltage boost IC after a second delay. The second delay is substantially longer than the first delay. The unboosted output voltage is sufficient to heat the filament windings but insufficient to initiate striking in the lamp(s), and the boosted output voltage is sufficient to initiate striking in the lamps. Thus, the filaments are pre-heated prior to striking in the period between the first and second delays.
