摘要： A partial-voltage buck regulator controls a high-voltage bus to a full-bridge circuit such that overall switching losses are reduced and distributed. Low-voltage buck regulator devices are PWM-switched when high output voltage is needed, and high-voltage bridge devices are PWM-switched when low output voltage is needed. A variable input power supply, which may be operated in a high power factor mode, can adjust the input bus voltages to achieve optimum performance for a given magnetic resonance imaging sequence.

摘要： A diagnostic circuit monitors filament currents in hot cathode fluorescent lamps for detecting when the filament erodes to the point of breaking. When such a filament failure is detected, information is processed and a request is sent to replace the lamp before it actually fails. The diagnostic circuit is low power and low voltage and is electrically isolated from the high-voltage end of the lamp. Additionally, a simple circuit to regulate rms value of filament voltage without having to compute or otherwise measure the actual rms value is provided.
