用于提高并联型开关-线性混合包络跟踪电源效率的边界调节滞环电流控制

The parallel-form switch-linear hybrid envelope tracking power supply is usually composed of a buck converter with hysteresis current control (HCC) and a voltage-controlled linear amplifier (VLA) connected in parallel. The buck converter is aiming to provide most of the load current for minimizing the output current of VLA to reduce its power loss. However, when the load voltage swing is large, th...
