PSU Design using IR2153 part 1
The main purpose of this design is for gas discharges using SDBD electrodes.
The desired voltage output is usually 10 kV or even higher, and at a frequency range from 5 kHz to 20 kHz, depending on the load.
Usually, a system like this contains several modules, including a signal generator that generates sine wave or square wave at desired frequency; a DC power supply module that converts the 220 V / 50 Hz AC input into DC; a DC chopper then converts this DC into square waves at desired frequency; after passing through a transformer, the final output square wave amplified and can be used to drive the load, which is a surface dielectric barrier discharge electrode.
A self-oscillating half-bridge driver was picked as it has an embedded oscillator that can generate square wave signal at a range of frequencies by adjusting Ct and Rt, as shown in the datasheet. The reason I was using this one was I DIDN'T have a function generator!!
Also in the datasheet, two typical connections are provided that can be used as a good reference.
So based on these connections, I designed my own circuitry using EasyEDA, because it's FREEEEE!
But, before sending the board to be printed, a concept examination was needed, so I soldered the parts on to a through hole board (not sure what are they called).
Darn! That's ugly. Forgive me, haven't been using the tools for a while.
Hope the test goes well.
