Divide and integrates modularization.
Further, the capacitance of the compensation filter on capacitance pcb board is six settings of a row.
Further, power driver module part integrates special driving circuit, and the locking of setting driving over-and under-voltage, overheat are protected
Shield, the protection of power device undersaturation and short-circuit protection circuit.
Further, three bolts hole are respectively uniformly arranged on power module cathode copper bar and power module anode copper bar, led to
Screw is crossed to connect with capacitance pcb board.
Further, plate is set to plate connection needle stand the first end of power module pcb board, and output copper post is set to work(
The second end of rate module pcb board, and be screwed on power module confluence copper sheet.
Compared with prior art, the beneficial effects of the present invention are:
1. capacitive module section is designed by modular combination, allow capacitance more reasonable layout in space and close to power
Device radiates to capacitance using aluminum hull；Capacitance module and power device are directly connected to by copper bar again, make driving implement
There is connection resistance low, power device electric current is evenly distributed, and the ESR values of capacitance are small, plays capacitance compensation electric current to greatest extent
Feature.
2. power driver module part uses modularized design, the heavy current circuit of power section is all using copper in module
Piece is connected with copper bar, and very big amplitude promotes electric current handling capacity, while module pressure drop is small, reduces module calorific value itself, capacitance
