Latest Patents

One of his latest patents is focused on mixed-mode power converter control. This invention involves circuits and methods for integrating a Current Mode signal into a Voltage Mode controller for fixed-frequency DC-to-DC power converters. The current-controlled voltage source (CCVS) generates a voltage that is proportional to the power converter output current. This voltage is then combined with a comparison signal that is generated by comparing a target output voltage to the actual output voltage. The modified comparison signal produces a pulse-width modulation control signal that regulates the power converter output based on both output voltage and a portion of output current. This innovation enhances stability and simplifies compensation across a wider operating range.

Another significant patent by Zanchi is a controller for a power converter. This invention addresses the lagging responses of a power converter to changes in circuit voltages or currents. It also mitigates over-shoot and under-shoot conditions when a target output voltage changes rapidly. The method includes scanning a feedback voltage from a load powered by the voltage output of a power converter controlled by a PWM control signal. It detects under-regulation conditions and increases the clock signal rate to improve the PWM control signal generation. This invention effectively limits the range of values for an M-bit count value to reduce under-shoot or over-shoot conditions.
