DC to DC Converters Solved Example - Power Electronics

What are the examples of DC to DC Converters?

A step up chopper will have an input voltage of 150V and required voltage output is 450V. it is known that the thyristor will have a conducting time of 150μseconds. Now, calculate the chopping frequency.
