Latest Patents
Tanabe's latest patents include innovative solutions that enhance the performance of DC-DC switching converters. One of his notable inventions is a slope voltage compensation circuit with an adaptive slope compensation method. This invention operates in current control mode at duty cycles greater than 50%. The proposed solution allows for the dynamic range of useful operation to be extended, lowering the slope voltage compensation at the beginning of the cycle, and then increasing the compensation as the 50% duty cycle is achieved. This method is based on voltage control instead of time, eliminating the need for a second phase of a clock.
Another significant patent is a system and method for operating a switching converter in light load conditions. This invention presents a switching converter that includes an inductor coupled to a pair of power switches, a signal generator, and a controller. The first power switch is used to magnetize the inductor, while the second power switch is used to de-magnetize it. The signal generator is designed to generate a modulated signal with a pulse width variable between a minimum and a maximum value, driving the power switches accordingly. Upon identifying that the modulated signal has reached the minimum pulse width value, the controller increases a reverse current flowing from the inductor through the second power switch to prevent the output voltage from exceeding a target value.
