This two- stage topology is based on a soft-charged switched-capacitor preregulator/ transformation stage and a high-frequency magnetic regulator stage. Soft charging of the switched capacitor circuit, zero voltage switching of the high-frequency regulator circuit, and time-based power density, and high power factor. The proposed architecture is applied to an LED driver circuit, and two implementations are demonstrated: a wide input voltage range dc–dc converter and a line interfaced ac–dc converter. The dc–dc converter shows 88%– 96%efficiency at 30-W power across 25–200-V input voltage range, and the ac–dc converter achieves 88% efficiency with 0.93 power factor at 8.4-W average power.

Light emitting diode devices promise unprecedented reductions in energy consumption in comparison to incandescent and fluorescent lights, but come with an as-yet unmet demand for high power density, high efficiency, and high-power-factor LED driver circuitry. An examination of commercial LED drivers illustrates this: considering a group of commercial line interfaced (120 Vac ) LED drivers in the 3–12 W output power range, and power factors of 0.73–0.93, with no systems achieving both high efficiency and high power factor. The switching frequencies of these drivers were in the range of 57–104 kHz, with all having correspondingly low power densities below 5 W/in3. Recently published academic designs are harder to fully evaluate and compare because of large variation on LED output configurations (e.g., separation to multiple LED loads or diverse LED voltage specifications), but appear to provide generally similar performance with moderate improvements in individual aspects. Overall, the volume of the converters was uniformly dominated by magnetic components, and in each case the driver circuit represented a major contribution to the LED system size. These examinations indicate that power electronics continues to be a significant limitation in solid-state lighting and that there is a need for major improvements in miniaturization and performance in this voltage and power range. .

The unregulated voltage, Vunreg is low so that the regulating stage can utilize fast, low-voltage devices operating at a high switching frequency to provide high- bandwidth regulation and a small additional voltage step-down. Since the regulation stage operates at a high frequency, the size of its passive components can be made small. By separating the transformation and regulation stage in this manner, the benefits typically associated with SC converters (i.e. high efficiency, high power density) can be preserved, while the main drawback (poor regulation) is done away with by the use of a separate magnetic regulation stage

The SC circuit can achieve high power density and efficiency at these frequencies because it employs only switches and capacitors and incorporates soft-charging operation. However, the SC converter alone cannot efficiently provide the fine voltage regulation capability needed in this application. Instead, this stage serves both to reduce the voltage range over which the second stage needs to operate, and to reduce the maximum voltage level (and hence impedance level) for which the second stage must be designed, in keeping with the design considerations described in the previous section. The second stage is a magnetic-based stage that provides both additional voltage transformation and fine voltage regulation, and is operated at high frequency (e.g., HF, 3–30 MHz) in order to minimize magnetic component size. High-frequency operation is more readily achieved with high efficiency in the second stage because it operates at lower voltages and smaller voltage range with voltage transformation of the SC first stage.

This approach is specifically designed to address the challenges of low-power conversion from high and wide-range input voltages. A soft-charged multimode SC converter stage is introduced that provides compression of an 8:1 input range to a 2:1 output range. Depending on operating mode, this topology provides partial or complete soft charging of the capacitors appropriate load. We detail operation of this reconfigurable transformation stage and also introduce appropriate drive and bootstrap techniques for it. We further show that merging this stage with a resonant transition discontinuousmode inverted buck converter enables conversion from a high, wide-range input voltage down to a low output voltage at greatly increased operating frequencies, and consequently greatly reduced magnetics size.
