Hello, i am trying to understand the circuit shown in the manual bellow.
There are two capacitors and in the middle of them there is capacitor and inductor connected to some bjt transisors.
Is there a a speciphic name for this circuit?
So i could understand how it works.
Thanks.

This is a more traditional half bridge power supply. Position 3 is the drive signal transmission transformer (two triodes, one is N type and one is P type), and position 2 is the main power triode. The two power transistors work alternately under the action of the drive signal polarity. The current circuit is realized by two series connected high-voltage electrolytic capacitor. The CBB capacitor on the transformer winding in series is used to isolate DC and prevent the transformer from magnetic bias. Typical drives are TL494, SG3525, or 3846. If there is an auxiliary power supply, the main controller can be on the high-voltage side. If you want to
