12 volts can be boosted to 60 volts by a transformer.
We usually use a transformer to reduce the voltage, such as the LED lamp transformer is 220 volts down to 12 volts. The transformer can also supercharge 12 volts to 60 volts.
A boost regulator chip such as the LM2585 (LM5000 higher voltage) can be used to convert 12V voltage to 60 volts. The current can reach 2 -- 3A, and the conversion efficiency is relatively high.
