Latest Patents

Zhan's latest patents include innovative methods and apparatuses for regulating power converters. One of his notable inventions is a power converter in peak current mode constant-off time control. This invention describes a device comprising a control circuit and a logic circuit that can be integrated into a controller coupled to the power converter. The control circuit generates a constant off-time signal based on a ramp signal and an error signal. The logic circuit produces a control signal based on both the constant off-time signal and a constant on-time signal. This invention allows for dynamic adjustments to the control signal based on the relationship between the off-time and on-time periods, optimizing the performance of the power converter.

Another significant patent is related to a current sharing scheme in current mode control for multiphase DC-DC converters. This invention addresses the need for effective current sharing between parallel converters in a multiphase configuration. It provides a cycle-by-cycle instant correction to the compensation signal offset based on the current share error, thereby improving the instant current share performance among the paralleled converters.
