Embodiment Construction
[0019] combined with figure 1 , 2 , 3, 4 describe an embodiment of the present invention.
[0020] A high-power DC motor steering controller is composed of an input control module 1 and a power output control module 2; the input control module 1 includes a forward rotation input control circuit and a reverse rotation input control circuit, and the power output control module 2 is composed of Four power MOS tubes are connected in parallel to form four sets of normally open contacts, and four sets of normally open contacts form an H-bridge control circuit; the forward rotation input control circuit includes two circuits, and the reverse input control circuit also includes two circuits; each circuit includes DC-DC power supply module, delay circuit, photoelectric isolation circuit and drive circuit. The DC-DC power supply module boosts the input control signal and sends it to the input terminal of the photoelectric isolation circuit. After the photoelectric isolation circuit is ...
