Outdoor LoRa-GPS tracker with E-Ink display Original project github.com/hutscape

The inverter specs are Switching frequency: 200kHz Input voltage: 180VDC Output voltage: 120VAC Max power: 1500W I have designed an Inverter schematic for an uninterruptible power supply (UPS), Used an efficiency LCL topology filter to eliminate 3rd and 5th harmonics as induction motor is connected at load. The Inverter schematic that can convert 180VDC into 120VAC, which can be used in any household or industrial application. You can refer the BOM to check the MOSFET parts, drivers, and filter parameter values.

A circuit allows a smaller control voltage to linearly control a larger output voltage.

How designed circuit works? When the battery is turned on, the high-frequency oscillator composed of the transistor Q2 and the step-up transformer T1 is energized using the 3V DC supply generating a high-frequency alternating current of about 18kHz, boosted by T1 to about 500V. This high voltage ranging at 500V is then further stepped up using a ladder network, which is made up of three 1N4007 Diodes, capacitors C2- C4. This network steps the T output to approximately three times its original value and we get around 1500V which gets stored inside a high voltage PPC capacitor positioned at the extreme end of the ladder network. Now for bug counter purpose, I am sensing the voltage on the output cap, I added a few diodes D1-D3 on the bottom side so that you see a high to low transition when a bug is zapped. This works only if the output cap is fully discharged when a bug is zapped, which is unlikely. Worth a try if you have some diodes around, and a fair amount of bugs too. Further, Arduino nano is used to count these output from the diode, and display on an LCD.
