The Pulse Power Amplifier for the Magnetic Bearing
There is presented PWM power amplifier for the inductance load. The PWM amplifier assigns to supply the active magnetic bearings which support shaft and flexible rotor. The power amplifier has got ten channels. The channels have got pulse bridge inverter with modulation PWM. There is showed construction, principle of operation, simulation and experimental result the PWM power amplifier.
