The invention relates to the technical field of battery charging circuits, in particular to a mining explosion-proof
lithium battery intelligent charging
system based on an IGBT (Insulated Gate Bipolar Translator)
power module, which comprises a
junction temperature change detection module, a duty ratio sectional control module, a
conduction channel constraint module, a
voltage channel correction module and a driving instruction integration module. According to the invention, a control
rhythm type is constructed based on a temperature change trend in an on-off period, a
rhythm sequence is formed through category screening, a duty ratio structure is established through a serial number associated
rhythm time sequence, a concentrated section is extracted in combination with current peak distribution to limit a conduction boundary, and a
voltage output rhythm is set according to a rhythm bit sequence. A
phase difference is extracted through a waveform structure to form an offset reference, and
control parameters are fused and output with rhythm switching identifiers in a ratio alternating sequence to form a
rhythm control flow adapted to load changes, so that the feedback efficiency and process stability of charging adjustment are improved, and the response capability of a power device and the rhythm matching degree of a
system are effectively enhanced.
