The bridge consists of four diodes with four lead pins. The connection point of the two diodes is the "positive pole" of the full-bridge DC output terminal, and the connection point of the two diodes is the "negative pole" of the full-bridge DC output terminal. The half bridge consists of two diodes with three lead pins. The pins on both sides of the half bridge are the positive poles of the diodes, i. e. the AC input, and the middle pins are the negative poles of the diodes, i. e. the "Positive Poles" of the DC output. Negative half, bridge on both sides of the pins on the two diodes negative, that is, AC input; intermediate pin is the two diodes positive, that is, the DC output of the "negative. ". A positive half bridge and a negative half bridge can form a full bridge.
