Abstract
An active bypass control device and an active bypass control method for a photovoltaic module are provided. The device includes a power source, a sampling unit, a controller, N first driving circuits, and N first controllable switches. Each first controllable switch is connected between one pair of bypass ports and includes a first switch and a first diode that are antiparallel. The first diode is reversely connected between the pair of bypass ports, and a control end of the first switch is connected to the controller via the corresponding first driving circuit. Based on a sampling signal provided by the sampling unit, the controller determines whether analog quantity information of the first controllable switch meets a predetermined bypass condition. If the predetermined bypass condition is met, the first switch is controlled to be turned on by using the first driving circuit.
