In this post I have explained a simple 48V inverter circuit which may be rated at as high as 2 KVA. The entire design is configured around a single IC 4047 and a few power transistors. .
Referring to the shown 48V inverter circuit, the IC 4047 forms the main oscillator stage responsible of producing a totem pole outputs for the connected output stage. The output stage is. .
C1 and R1 must be appropriately set for achieving the desired frequency as per the required specifications. could be 50 Hz or 60 Hz. The shown 48 V inverter configuration is designed to generate a massive 2 kva of output power provided the devices are. .
In the above explained 48V inverter circuit I have used a BC546 emitter-follower series pass circuit to step down the 48V DC to 9V DC for supplying the IC 4047. However, if the BC546 transistor is not available, we can incorporate a zener/resistor based.
