Configuring Switched-Capacitor Power Converters Using Interleaving Regulation Techniques

Due to their inherent switching operations, both switch mode and SC power converters exhibit output voltage ripples and current ripples, which lead to substantial switching noise. The switching actions in many power converters can cause their input current to be discontinuous. This can generate severe di/dt noise, which will propagate into the entire system. In the meanwhile, a discontinuous output current can severely impact the load regulation performance of SC converters. Such converters will respond to sudden load changes only at the start of the next switching cycle, which can cause large output voltage variations.
