In this post I have explained how to correctly calculate inverter parameters with associated stages such as battery and transformer, by calculating the matching the parameters correctly. Introduction Making an inverter all by yourself can be definitely lot of fun. However if the results are not satisfactory can completely spoil the whole purpose of the […]

Homemade 2000 VA Power Inverter Circuit
Making a power inverter circuit rated above 2000 VA is always difficult, mainly because of the involved transformer dimension which becomes quite huge, unmanageable and difficult to configure correctly. Introduction Power inverters in the range of KVA, requires huge current transferring capabilities for implementing the required operations as per the desired specs of the unit. Transformer being the main power […]
Convert any H-Bridge Inverter to Sine Wave H-bridge Inverter
In this post we’ll discuss how to convert any ordinary square wave H-bridge inverter into an almost pure sine wave inverter circuit. Basic Concept The idea is simple, just chop the low side MOSFET gates of the H-Bridge with reverse SPWM (Sinusoidal Pulse Width Modulation) waveform. This will force the low side 50 Hz, or […]
Simple 48V Inverter Circuit
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. Technical Specifications I am a big fan of u….i am a wisp. i need an inverter design with 48volt […]
Automatic Inverter Output Voltage Correction Circuit
The common problem with many low cost inverters is their incapability of adjusting the output voltage with respect to the load conditions. With such inverters the output voltage tends to increase with lower loads and falls with increasing loads. The circuit ideas explained here can be added to any ordinary inverter for compensating and regulating […]
