Abstract: A power system is provided. The power system includes a multi-level DC/DC converter electrically coupled with a terminal of a voltage source, such as a battery. The power system includes an EMI filter network having EMI shunt filters electrically coupled between the terminals of the battery and a reference frame or grounding system. The EMI shunt filters each include at least one of a first order filter and a second order filter. The elements of these ordered filters can be used to shunt common mode electric current to less-resistive paths, limit voltage, and reduce common mode voltage noise to ultimately reduce the common mode effects in the power system.

Abstract: A ballast for driving a gas discharge lamp includes an inverter configured to generate a lamp supply voltage signal, and a voltage regulator coupled to the inverter and configured to generate a regulation signal. The regulation signal is used by the inverter to maintain the lamp voltage signal at a substantially constant voltage. A thermistor circuit is coupled between the lamp supply voltage signal and the voltage regulator and configured to detect a temperature of the ballast. The lamp supply voltage signal is varied by the regulation signal in accordance with the detected temperature of the ballast.

Abstract: A timing circuit may be enabled when a static signal disables communication through a communications bus, the timing circuit producing a threshold level after being enabled for a predetermined time period, and a switch controlled by the timing circuit is configured to disconnect the static signal when the timing circuit produces the threshold level. A static signal may be used to enable a timing circuit upon the static signal disabling communication through a communications bus, and communication may be allowed through the communication bus by disconnecting the static signal using a switch controlled by the timing circuit, after the timing circuit has been enabled for a predetermined period of time.

Abstract: Provided is a lighting ballast system and method for fluorescent lamps. The system and method utilize a lamp current control loop to control the light level of a fluorescent lamp. The ballast includes an open loop detector that recognizes an open current control loop as an indication of a fault or hazard condition, and causes the ballast to output a safe lamp voltage or no voltage. The fault or hazard condition may be, for example, a very high voltage at the lamp or very low current across the lamp. The ballast also includes a disable circuit that prevents the open loop detector from triggering at times when the loop is expected to be open such as during ignition and maintenance restarting of the lamp.
