摘要： Control loop ripple voltage in an error amplifier may be the result of a non-linear time varying behavior of a switch mode power conversion process. An inverse waveform replica of the error amplifier control loop ripple voltage waveform may be generated to substantially cancel the non-linear loop dynamics introduced by the control loop ripple voltage. Once the control loop ripple voltage is substantially cancelled the bandwidth of the DC-to-DC converter control loop may be increased for faster loop response thus reducing the need for additional output filter capacitance.

摘要： In a method and system for providing isolated power, a flyback controller includes a transformer operable to receive a primary voltage input and generate a secondary voltage output. A switch electrically coupled in series with a primary side of the transformer receives a control signal for controlling a duty cycle of the primary voltage. A controller is operable to generate the control signal responsive to receiving a plurality of inputs from the primary side. The controller regulates the secondary voltage output without receiving feedback input from a secondary side of the transformer by computing the secondary voltage as a predefined function of the plurality of the inputs when the switch is open.

摘要： Power supply response to variations in power demand by a microprocessor is improved with a compensation loops that estimate changes in load current with improved speed. The load current estimate is performed in part with a capacitance feed forward compensation loop that senses voltage at output capacitors to replicate the current present in the capacitors and communicates the capacitor current adjusted by an optimized gain to the power supply for adjustment of power output. Capacitor current is replicated with a frequency domain filter having a pole that cancels out the zero created by power supply equivalent series resistance and capacitor capacitance. The capacitance compensation loop improves power supply response time to microprocessor power demand skews so that the size or number of output capacitors may be reduced while still maintaining power supply at the microprocessor to within desired voltage and current tolerances.

摘要： A circuit for suppressing transients in a voltage regulator due to a load step transient in the demand of the load. The circuit includes a suppressor element that is placed in the current path of the inductor of the switching regulator in response to a determination of an over voltage condition. The suppressor element pulls the voltage level of one side of the inductor below a particular potential, such as, e.g., system ground. Examples of suppressor elements that may be used include zener diodes, diodes, capacitors, resistors, and negative voltage sources. When the current through the inductor has subsided to a particular level, the suppressor element may be removed from the inductor current path, wherein the energy stored in a bulk filter capacitor may be drained through the inductor to the system ground. The suppressor circuit may be used in a information handling system or other type of electronic system.

摘要： An information handling system includes a power converter having a first switched inductor to supply current to a load. A second switched inductor is inductively coupled to the first switched inductor. A control circuit activates the second switched inductor in response to a change in the power requirements of the load, so as to remove energy stored in the first switched inductor and thereby regulate the output voltage of the power converter when load current is stepped downwards.

摘要： A bi-directional energy storage module and method of operation is disclosed. The converter includes an inductive component, an energy storage element, two diodes and two switches. One switch is positioned in a first sub-circuit between an input voltage source and the inductive component and the other switch is positioned in a second sub-circuit between the inductive component and the energy storage element. The inductive component can be an inductor or a transformer. The energy storage element can be a battery or a capacitor. A hysteretic control structure can be used to activate and control the charging and discharging modes of operation. Voltage across the energy storage element and current through the inductive component are monitored. The switches are controlled to keep the monitored parameters within established bounds. Inrush current problems are eliminated and simple gate drive mechanisms are facilitated. The invention can be used in battery charging and discharging applications. The invention can also be used in an energy storage module of a system providing an uninterrupted power supply.
