摘要： A self-oscillating boost converter includes a resistor-starting network configured to start a charging of the boost converter. A resonant feedback circuit is designed to generate an oscillating signal following the starting of the circuit by the resistor-starting network. A complementary switching network has a pair of complementary common-source connected switches configured to receive the oscillation signal generated by the resonant feedback circuit. The oscillation signal determines a switching rate, or duty cycle, of the complementary pair of switches. A boost inductor is in operational connection with the complementary pair of switches. The switching rate of the complementary switching network acts to determine the boost voltage supplied to a load.

摘要： A ballast circuit for a gas discharge lamp of the type including resistively heated cathodes includes a resonant load circuit incorporating a gas discharge lamp and including first and second resonant impedances whose values determine the operating frequency of the resonant load circuit. Further included is a d.c.-to-a.c. converter circuit coupled to the resonant load circuit so as to induce an a.c. current in the resonant load circuit. The converter includes first and second switches serially connected between a bus conductor at a d.c. voltage and ground, and has a common node through which the a.c. load current flows. A feedback circuit provides a feedback signal indicating the level of current in the resonant load circuit. A high voltage IC drives the first and second switches at a frequency determined by a timing signal which predominantly comprises the feedback signal during lamp ignition, whereby during lamp ignition the feedback signal causes the high voltage IC to drive the first and second switches towards a switching frequency which promotes resonant operation of the resonant load circuit. A circuit isolates the feedback signal from the timing signal for a predetermined period of time upon energizing of said converter circuit so as to allow the cathodes to become heated during such period of time, prior to lamp ignition.

摘要： A ballast for a gas discharge lamp comprises a resonant load circuit including a gas discharge lamp, and a resonant inductance and a resonant capacitance whose values determine the operating frequency of the remnant load circuit. A d.c.-to-a.c. converter circuit is coupled to the remnant load circuit to provide a.c. current to the remnant load circuit. The converter comprises at least one switch. A high voltage IC drives the at least one switch at a frequency determined at least in part by impedance between a timing input and a ground. A circuit for supplying a d.c. voltage to the d.c.-to-a.c. converter includes (i) a supply path for d.c. current; (ii) first and second return paths for d.c. current; and (iii) an arrangement to selectively make the first return path operable alone, the second path operable alone, and the first and second paths operable together. First and second impedances are coupled between the timing input and the first and second return paths, respectively. A second, one-way current valve isolates the second impedance from the ground when the second current path is rendered inoperable. A first, one-way current valve isolates the first impedance from the ground when the first current path is rendered inoperable. A second, one-way current valve isolates the second impedance from the ground when the second current path is rendered inoperable. When the lamp comprises resistively heated cathodes, a cathode current-controlling, frequency-dependent impedance is preferably connected between the resistively heated cathodes.

摘要： A circuit and method for powering a high intensity discharge lamp, such as a high pressure sodium lamp (HPSL) are disclosed. Feedback control is used to achieve a nearly constant amplitude of lamp current so as to attain nearly constant lamp color in a HPSL, and further accommodates considerable variations in a.c. line voltage. The circuit, which shares some features with the method, includes a circuit to supply a d.c. bus voltage and first and second feedback-controlled circuits. The first feedback controlled circuit regulates the bus voltage in response to a first error signal which is derived as a function of peak lamp current and a set point signal for such peak current. The second feedback controlled circuit regulates lamp power in response to a second error signal which is derived as a function of average bus current and a set point proportional to the difference between regulated bus voltage and lamp power.
