Latest Patents

Zhang's latest patents focus on the design and control of DC to DC converters. In his innovative controller for a DC to DC converter, he has developed PWM (Pulse Width Modulation) signal generating circuitry that produces a set of PWM signals that are phase-shifted relative to one another. This circuitry controls the states of the PWM signals based on a set of control signals. Each PWM signal has distinct on-time and off-time states. Additionally, ramp signal generating circuitry is coupled to the PWM signal generating circuitry, producing ramp signals with a consistent ramp slope. These ramp signals are generated in response to detecting the on-time state of the corresponding PWM signals. A comparing circuit, which is also coupled to the PWM and ramp signal generating circuitry, alternately compares the ramp signals with a preset reference to generate the control signals. This innovative approach allows for precise control of the PWM signals, enhancing the overall performance of the DC to DC converters.
