3000w inverter circuit diagram jobs

This is mainly a basic circuit design. I want an undervoltage and overvoltage cutoff circuit for 240V AC mains. The functional requirements are such: Min Voltage: 100V Max Voltage: 290V Max Power drawn: 300W (for eg. 1.2A@250V, or 3A@100V) The input circuit should be cutoff outside the min-max voltage range (variable). Also, it should be a non-relay cutoff. So you can think of triacs or mosfets or anything else. I want the circuit alongwith the Material list (eg. 12V transformer, diodes etc.).

I'm looking for someone to design a protection circuit for a 24V dc motor. The problem to overcome is that under certain, unusual ,fault conditions the motor can remain powered for prolonged periods resulting in a motor burn out. The motor is usually driven forward and backwards by software control with drive applied for no longer than around 20 seconds at any time in either direction. The protection circuit should help to prevent motor burn out by recognising an anomaly such as power applied in excess of 90 seconds at which point the output power should be removed. The circuit should be able to automatically reset once input power has been removed. The load current of the motor is usually no greater than 1.0amps and is typically limited to 500mA. The ideal candi...
