Latest Patents

Jie Zhang's latest patents include a "CCM-based fly-back switching power supply circuit and control method thereof." This invention features a constant current control circuit, a sampling circuit, and a peak current control circuit. The sampling circuit samples the ON-time of the secondary coil to obtain its duty cycle signal D_SEC, which is then sent to the constant current control circuit. The constant current control circuit generates a voltage signal CAC from the duty cycle signal D_SEC and a preset reference voltage signal VREF. It converts these signals into time signals and outputs an adjustment signal CCOUT to adjust the peak current control signal VCST, ensuring the fly-back switching power supply circuit outputs a constant current.

Another significant patent is the "Constant-current output control circuit and its design method." This circuit includes a control module, a first resistor, a capacitor, and an error amplifier. The control module connects to an adjustable control voltage and a detection signal. The error amplifier's non-inverting input connects to the reference voltage, while its inverting input connects to the first end of the first resistor. The design method of this circuit is also disclosed, showcasing Jie Zhang's expertise in circuit design.
