Power supply circuit (experts welcome) [Copy link]

Our company is currently using: power transformer: input is 230V, 50HZ. Output is 38V and 18V, load voltage is 29V and 15.5V, current is 1.8A and 0.1A. Since the price of power transformer is too high, can we use high-frequency transformer instead?

You can use a switching power supply instead, but you didn't make it clear whether you are using a switching power supply, and what are the requirements for power supply efficiency and ripple.
