There are all manner of DC-DC boost and buck converters that will do yeoman service for you, the buck converters are a few bucks ($3-6), and there is a nice 45-390V boost converter from several sources for around $10.00. (There are two versions- a bi-polar, and a positive only, don’t get the bipolar unless you need it, as it is half the current) They will deliver up to 30W over the output voltage range. I have used them as dynamotor replacements, literally fitting the converter in a gutted dynamotor case. I have used literally dozens of these over the last 5 years, and find they work very well, with quite high efficiency.
