Final answer:
To address insufficient current output in rectifier units of CAC-A, examine the rectifiers and diodes for issues, replace with higher capacity units or connect multiple rectifiers in parallel to boost current output.
Step-by-step explanation:
When the rectifier units in a circuit associated control or power system (CAC-A) do not have sufficient current output, it is recommended to first identify if the issue lies with the rectifier itself or with the secondary coil's ability to provide the necessary current. The rectifier converts alternating current (AC) from the secondary coil into direct current (DC), which is done with the help of diodes that allow current to flow in only one direction. If the current output is insufficient, one possible solution is to either replace the rectifier units with ones that have a higher current capacity or to parallel multiple rectifiers to increase available current. It's also important to check that the diodes are not damaged or degraded, as this could affect the performance of the rectifier.
