# Why voltage drop accross a load is higher in case of inverters? [closed]

I have built an inverter circuit, where the circuit works properly for light AC loads e.g. 9 watts, 230V LED bulb etc. and gives an output voltage of 200v, but if I use a 70 watts, 230V exhaust fan as my load, it doesn't work and voltage across the load is found to be 30V. What is the problem and what should I do, to make it work properly for any load?

I have attached my schematic diagram:

• I have attached my circuit diagram No you haven't, that's not a circuit diagram. Circuit diagrams use proper symbols for components and look like: i.stack.imgur.com/NUxu0.png Your drawing just shows how to connect the components, it gives no information about the functionality of those components. A proper circuit diagram does show that. – Bimpelrekkie Jan 8 at 8:26
• What's the rated output of this circuit? What do you expect if you connect for example a 2 kW load? – pipe Jan 8 at 8:30
• Rated output voltage is 200V at light AC load and using heavy loads like AC Motor, the Voltage ouput is around 30v, why? If I connect any load it should work properly without any voltage drop, what should l do? – al rizwan khan mehboob ali Jan 8 at 10:03
• No inverter works at any load. You seem to have copied this from somewhere, so you need to find documentation about it. – pipe Jan 8 at 10:17
• "Rated" means "how much it was designed for." You have told us what it really produces, not what it was designed to produce. – JRE Jan 8 at 12:00
