<p>A direct-current bidirectional controller, which controls an inputted direct-current power supply, so as to realize a bidirectional full-wave output that a positive electrode of a 4.5-36V direct-current power supply alternately converts with a negative electrode thereof. The bidirectional controller comprises a chip IC1 and an H-bridge circuit controlled by the chip IC1. By adopting the IC chip and a crystal triode as major elements for amplifying power and converting between the positive electrode and the negative electrode, the bidirectional controller reduces costs and decreases energy consumption. The bidirectional controller is suitable for being used as a low power controller of a light string for alternately converting between the positive electrode and the negative electrode of the 4.5-36V direct-current power supply.</p> |
