Latest Patents

Yedevelly's latest patents include innovative designs that enhance the efficiency of voltage regulators. One of her notable inventions is the "Synchronous VCC generator for switching voltage regulator." This technology involves charging a capacitor synchronously with the beginning of an ON portion of a pulse width modulated (PWM) signal. The capacitor generates a voltage using charging current sourced from an inductor on the primary side of a transformer. This voltage serves as a supply voltage for control circuitry in an integrated circuit that generates the PWM signal. The charging process is halted when the charging current exceeds a predetermined level or when the capacitor voltage surpasses a specific threshold.

Another significant patent is the "Primary side sensing for isolated fly-back converters." This invention allows a switching voltage regulator to sample signals corresponding to a flyback voltage on an auxiliary winding on the primary side. The flyback voltage acts as feedback from the output voltage on the secondary side. Upon detecting the presence of the flyback voltage, the regulator stores samples until the voltage falls below a threshold. This method maintains a history of samples, ensuring that the control for output voltage generation is based on the most relevant data.
