Design a Microprocessor based sensorless high-speed permanent magnet synchronous motor inverter circuit. Your basis for the design is in the technical paper attached for PM Motor specs. and a schematic diagram of the circuit to be designed. Pseudo-Current-Source Inverter. PEDS2005_takata.pdf.

The motor controller circuit you will design will be driven by a 12v DC bus. (Automobile 12vdc battery) Therefore the Buck Boost and Buck Chopper circuit needs to be designed to increase the 12Vdc bus voltage to a higher DC voltage to power the six-step inverter. Perhaps as high as 72Vdc. MOSFETS with 60-V and 150-A ratings.

What I need:

A complete set of schematics for a Controller Drive Circuit design. Buck Boost and Buck Chopper circuit design, Six-step inverter circuit, peak current 75 A or greater. PAM, integrator, comparator and isolator and logic, F/V, e.m.f. based circuit.

The microcontroller choice can be FreeScale or MicroChip. I am attaching a sensorless PMSM applicat...
