 Voltage Regulatory 0V - 60V With 100A

The number of transistors are actually not accurate, for 100 amp current there must be at least 15 transistors of TIP142. More the numbers cooler will be the transistors.

The current through the transistors will depend on the load, not on the voltage adjustments. But yes wider input/output differential will cause the transistors to heat up a lot, that’s the drawback of all linear power supplies. To correct this, the input voltage range from the SMPS must be reduced appropriately.

Protection has not been provided, you can add a current limiting by adding a common 2N2222 limiting circuit network.
