20090059632 | System And Method For Controlling A Current Limit With Primary Side Sensing Using A Hybrid PWM and PFM Control - A hybrid constant current control system that uses both pulse width modulation (PWM) and pulse frequency modulation (PFM) control. When transitioning from constant voltage mode to constant current mode the present invention can continue to control using PWM. Thereafter, when the voltage has dropped, the present invention smoothly transitions to PFM mode. The point of transition is based upon the switching frequency and the lowest rated voltage of operation. The system and method avoids very short (narrow) Ton times which ensures accurate constant current (CC) control with bipolar junction transistor (BJT) devices. The present invention also avoids acoustic noise because the switching frequency is maintained at a high enough level to avoid such acoustic noise even when the energy transferred through the transformer is still substantial and the output voltage is not too low. In addition the output current limit is insensitive to variation in the inductance-input voltage ratio, and is minimized against leakage inductance. | 03-05-2009 |

20100164455 | ADAPTIVE MULTI-MODE DIGITAL CONTROL IMPROVING LIGHT-LOAD EFFICIENCY IN SWITCHING POWER CONVERTERS - Adaptive multi-mode digital control schemes that improve the light-load efficiency (and thus the overall average efficiency) in switch-mode power converters without causing performance issues such as audible noises or excessive voltage ripples. Embodiments include a switch-mode power converter that reduces current in the power converter using a second pulse-width-modulation (PWM) mode before reaching switching frequencies that generate audible noises. As the load across the output of the power converter is reduced, the power converter transitions from a first PWM mode in high load conditions to a first pulse-frequency-modulation (PFM) mode, then to a second PWM mode, and finally to a second PFM mode. During the second PFM mode, the switching frequency is dropped to audible frequency levels. Current in the power converter, however, is reduced in the second PWM mode before transitioning to the second PFM mode. Therefore, the power converter produces less or no audible noise in light load conditions where the switching frequency drops to audible frequency levels, while achieving high efficiency across varying load conditions. | 07-01-2010 |
20100208500 | Detecting Light Load Conditions and Improving Light Load Efficiency in a Switching Power Converter - A switching power converter detects low load conditions based on the ratio of a first peak current value for peak current switching in constant voltage regulation mode to a second peak current value for peak current switching in constant current regulation mode. The power supply load is considered to have a low load if the ratio is lower than a predetermined threshold. Once a low load condition is detected, the switching frequency of the switching power converter is reduced to a level that minimizes switching loss in the power converter. In addition, the switching power converter also adjusts the switching frequency according to the sensed input line voltage. An offset is added to the switching period to reduce the switching frequency of the switching power converter, as the input line voltage is increased. | 08-19-2010 |
20100225293 | ADAPTIVE CONTROL FOR TRANSITION BETWEEN MULTIPLE MODULATION MODES IN A SWITCHING POWER CONVERTER - In a switching power converter, PWM mode and PFM mode are separated into two independent control sections with the control voltage range in each control section determined independently. Each of the PWM and PFM modulation modes cannot operate continuously beyond its boundaries, thereby forming a control gap between the two control sections within which no continuous operation is allowed. In order to supply a load condition within the control gap, the power supply operates at the two boundaries of the control gap. Transition between PWM and PFM modes occurs fast, with low output voltage ripple. No limitation needs to be imposed on the control voltage range in each of the PWM and PFM control sections, because the control parameters in the PWM and PFM control sections need not be matched to one another, due to separation of the PWM and PFM modes by the control gap. | 09-09-2010 |

The dead time and baseline on-time are used in calculating the desired on-time of the switch during a subsequent switching cycle of the power converter. The desired switch on-time regulates the output voltage to a desired voltage level.

20120302731 | PROTEIN HYDROLYSATE, POLYPEPTIDE SOLUTION AND POLYPEPTIDE, PREPARATION METHOD AND USE THEREOF - The present invention provides methods for the preparation of protein hydrolysate, peptide solution and peptide from BSG. The wet BSG or BSG powder is dispersed in extract solution to prepare the crude BSG protein or the crude BSG protein solution. Preparing the crude BSG protein solution using the crude BSG protein and adjusting the pH to 6.5˜8.5, or adjusting the pH of the crude BSG protein solution to 6.5˜8.5. Then the solution is hydrolyzed with protease at 45° C. to 65° C. for 1 h to 5 h in a water bath shaker to prepare BSG protein hydrolysate. The protein hydrolysate is heated to inactivate the protease and centrifuged to obtain the peptide solution. The peptide solution is separated by gel filtration and each peak is collected and pooled together to obtain the peptide. The protein hydrolysate, peptide solution and peptide in the present invention are all prepared from BSG which is a natural product and available at low cost throughout the year. There is no harmful material used in the production process. The results of in vitro experiment suggest that BSG peptide prepared by this method shows a significantly hypoglycemic effect. | 11-29-2012 |
