Latest Patents

Among Zhiye Zhang's most recent inventions are two notable patents that demonstrate his expertise in switching regulator design. The first patent introduces a switching regulator implementing negative current protection. This innovation features a controller that includes a protection circuit designed to limit negative current to a defined threshold, effectively preventing damage to the power switches during operation. When the negative current reaches this threshold, the protection circuit automatically turns off the low-side power switch while engaging the high-side power switch for a predetermined time. If the negative current does not recover, both switches are turned off, although the high-side switch allows current to flow through its body diode until recovery occurs.

The second patent, a constant on-time switching regulator for zero ESR output capacitor without output voltage offset, includes a control circuit that employs a fixed frequency constant on-time control scheme. This design features a reference voltage generator that produces a voltage ramp throughout the switching period, enhancing stable feedback control without introducing voltage offsets for any output voltage values. This approach grants the switching regulator flexibility in utilizing output capacitors with various ESR values, including those with low or zero ESR.
