20200403498 | SYSTEM AND METHOD TO ENHANCE SIGNAL TO NOISE RATIO AND TO ACHIEVE MINIMUM DUTY CYCLE RESOLUTION FOR PEAK CURRENT MODE CONTROL SCHEME - Systems and methods for providing peak current mode control (PCMC) for power converters. Noise immunity is improved by enhancing the signal-to-noise ratio of an inductor (or switch) current to achieve minimum duty cycle resolution and eliminate subharmonic operation that causes high input and output ripples. Current is sensed and translated to a voltage by a current sense resistor for peak current mode control scheme. A direct current (DC) offset voltage is added only during an on-time of the main switch to increase the signal-to-noise ratio. A leading-edge spike caused by turn-on of the main switch is removed by resetting a filter capacitor of a current sense circuit to zero volts after each switching cycle. | 2020-12-24 |
