Dynamic duty cycle control cuts AC output THD in a power inverter by detecting step-up loads and briefly raising switching duty cycle.
A hysteretic ripple filter shifts energy between DC bus and storage capacitors to cut bus capacitance, smooth voltage, and avoid electrolytics.
Low-frequency soft charging in a stacked switched capacitor buffer cuts twice-line-frequency loss and avoids unreliable electrolytic capacitors.
Variable delay settings in a motor driver bridge circuit minimize dead time to prevent through current without sacrificing torque or power efficiency.
