[0019] Attached 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 input control circuit. The power output control module 2 consists of Four power MOS transistors are connected in parallel to form four groups of normally open contacts, and the four groups of normally open contacts form an H-bridge control circuit; the forward rotation input control circuit includes two channels, and the reverse input control circuit also includes two channels; each channel includes DC-DC power module, delay circuit, photoelectric isolation circuit and drive circuit. The DC-DC power module boosts the input control signal and transmits it to the input end of the photoelectric isolation circuit. The photoelectric isolation circuit is delayed by the delay circuit Tur...
