Latest Patents

Virginia Li holds a patent for a "Current mode control DC-DC converter with single step load transient response." This invention involves a power converter that utilizes constant on-time (COT) or ramp pulse modulation (RPM) control. It achieves a more rapid resumption of steady-state operation after a step-up load transient. This is accomplished by extending the on-time of a switching pulse through the interruption of a ramp voltage waveform. The ramp voltage is compared with a threshold that equals a threshold voltage at the termination of a switching pulse or by increasing a voltage with which the ramp voltage is compared. These techniques are applicable to both single-phase and multi-phase power converters.
