Latest Patents

One of Bari's latest patents is titled "Inverse charge current mode (IQCM) control for power converter." This invention estimates the amount of charge transferred by a power converter by developing a signal that combines the output voltage and inductor current of the converter. The method involves charging a capacitor with a current proportional to this signal and comparing the voltage across the capacitor to initiate a pulse for controlling input power from a voltage source. This approach improves the response to both step-up and step-down transients and addresses ripple cancellation issues in multi-phase embodiments.

Another notable patent is "Transient performance improvement for constant on-time power converters." This invention enhances the response of a variable frequency switching constant on-time or adaptive on-time controlled power converter to significant changes in load. It employs a simple circuit that detects the magnitude and polarity of output voltage changes, allowing for the initiation, extension, or termination of power pulse conduction. This innovation reduces the amplitude and duration of transient response undershoot or overshoot, and it can also minimize the capacitance of an output filter while maintaining comparable transient performance.
