A ballast () for powering a lamp load () comprising one or more gas discharge lamps () includes an inverter (), a resonant output circuit (), and a control circuit (). During operation of ballast (), control circuit () monitors at least one voltage within one or more series resonant circuits of output circuit (). When the monitored voltage reaches a specified level, control circuit () directs inverter () to maintain its operating frequency at a present value for a predetermined period of time, so as to allow output circuit () to provide a suitably high voltage for igniting the lamp(s). If the lamp(s) ignite within the predetermined period of time, control circuit () ceases controlling inverter () to maintain its operating frequency at the present value, so as to allow for normal operation of the lamp(s). Control circuit () also provides a lamp stabilization function, in which the inverter operating frequency is prevented from falling below a specified minimum value, and a protective function, in which inverter () is deactivated in response to failure of the lamp(s) to ignite within the predetermined period of time.

During the preheat phase, resonant output circuit () has an effective resonant capacitance corresponding to the first resonant frequency, and provides a first level of heating to the lamp filaments (). During the normal operating phase, resonant output circuit () has an effective resonant capacitance corresponding to the second resonant frequency, and provides a second level of heating to the lamp filaments () that is negligible in comparison with the first level of heating. Control circuit () monitors a voltage within resonant output circuit () in order to compensate for any variation in the parameters of resonant output circuit () and to ensure that an appropriate level of preheating is provided to lamp filaments ().

A ballast comprises an inverter having a transformer comprising a core, a primary winding, and a secondary winding for connecting to a lamp and providing voltage thereto. The ballast includes a fault condition detection circuit connected to the inverter for disabling the inverter to discontinue energization of the lamp when a fault condition occurs. The fault condition detection circuit comprises an other primary winding wound on the core of the transformer for receiving a voltage signal proportional to a voltage across the secondary winding, a voltage blocking circuit connected to the other primary winding for receiving the voltage signal from the other primary winding, and a capacitor connected between the voltage blocking circuit and ground potential. The voltage blocking circuit is configured to selectively conduct and block the received voltage signal as a function of the frequency of the received voltage signal.

An electronic ballast () for powering at least one gas discharge lamp () includes a current-fed resonant inverter () and a load shed circuit (). Inverter () ordinarily powers the lamp at a first level. When a load shed command is sent by the electric utility and received by an associated load shed receiver within the ballast (), load shed circuit () causes the inverter to reduce the lamp power from the first level to a second level. Preferably, load shed circuit () includes an isolation circuit () and a bidirectional switch () that is coupled in parallel with a return ballasting capacitor () within inverter (). In the absence of a load shed command, bidirectional switch () effectively shunts return ballasting capacitor (), which causes the lamp to be powered at the first level. In response to a load shed command, bidirectional switch () ceases to shunt return ballasting capacitor (), thereby causing the lamp power to be reduced to the second level.

Preferably, output circuit () is a non-isolated circuit that includes a current-limiting inductance, and inverter () includes a frequency control circuit (R,C,C,Q,R,R,C) for operating the inverter at a higher frequency during the initial period so as to reduce stress upon the lamp filament and preserve the operating life of the lamp. The circuit () is especially suitable for powering low voltage halogen lamps.
