| Abstract |
The paper describes a microprocessor based Uninterruptible Power Supply Control Unit which employes two microprocessors: one generates the Pulse Width Modulation control signal and the other one executes diagnostic and supervision functions. The most interesting characteristic of the control unit is the great adaptability which allows the use of this circuit for the best control of many power units: the control unit is able to drive power circuits made up with different kinds of semiconductor devices as SCRs, GTOs, Power Transistors and MOSFETs. The microprocessor based control unit may also be used for the control of an additional input circuit of the converter which modifies the rated voltage of the battery systems in order to employ different kind of storage cells. |
