摘要： An illumination system includes a power supply having a boost converter operating in the discontinuous conduction mode, a flyback converter operating in the critical conduction mode, and a switch coupled to the flyback converter. Several light emitting diodes receive power from the power supply. The boost converter may include a boost inductor (LB) and a boost diode (DB), constructed to perform the boost power factor correction (PFC) function. The flyback converter may includes a flyback inductor (LFB) and a flyback diode (DFB) and the power supply may be constructed to turn on the switch around the point where the current flowing in the flyback inductor reaches zero value.

摘要： A high-voltage power supply and regulator circuit for an X-ray tube which utilizes solid-state switching devices with feedback control for real time monitoring and protection against failure due to excess current or voltage spikes. The apparatus includes a DC supply circuit utilizing a first feedback control loop and silicon controlled rectifiers to regulate the output of a high-voltage transformer. The apparatus further includes a regulator circuit utilizing a second feedback control loop and a series of FETs to produce a continuous or pulsed output of precise magnitude and phase. Shielded voltage dividers are provided to accurately measure the voltage outputs and produce feedback control signals. Discharge modules on the high-voltage cables connecting the power supplying X-ray tube discharge any capacitive voltage remaining on the cables between pulses, so as to eliminate any tail on the output waveform. A current measuring apparatus and excess current detector are provided to protect against excess currents. Patient dosage feedback is derived from an X-ray exposure sensor placed behind the patient receiving the X-ray radiation. At one or more times during the initial exposure period, the output of the X-ray tube is modified in order to obtain a 100% density image while minimizing the patient exposure.
