摘要： A man machine interface for an A-C motor bypass has a membrane keypad with a multiplicity of pushbuttons connected to a micro-controller. The micro-controller controls the flow of current to the coil of each of the drive and bypass contactors to thereby open or close those contactors depending on if the motor is to be driven and how it is to be driven. The micro-controller includes code that simulates a first state machine that determines the operating condition of the drive and bypass contactors and if it is desired to open that one of the two contactors which is presently open and close that one of the two contactors when is presently open. The micro-controller includes code which simulates a second state machine which is active only when the inverter contactor is open. This state machine determines if the motor is to run or stop and closes or opens the bypass contactor accordingly. The micro-controller includes a non-volatile memory that is used to store the last operating mode of the bypass operating condition if that mode was either automatic operation of the motor, that is, the motor is connected to an A-C source through the inverter in the bypass, or off.

摘要： In a neutral-point-clamped power inverter, gate drive circuit comprises four drive blocks providing bipolar DC signals to control switch gates. The first and third drive blocks are bootstrapped to the second and fourth. Inverter's neutral bus is commonly connected to the positive and negative DC buses through clamping capacitors. An arm of four serially-stacked-switches bridges DC buses. The switch arm midpoint is an output of the inverter. A first clamping diode connects the neutral bus to the first switch emitter; a second clamping diode connects the neutral bus to the third switch emitter. In one embodiment, a second switch arm mirrors the first, providing a second output; a second gate drive circuit mirrors the first. A bias circuit provides two reference voltages for the gate drive circuits. Three isolated DC sources provide signals that, when used by the gate drive circuit, result in seven isolated bipolar DC signals.

摘要： A voltage converter includes a transformer with a pair of primary coils and a secondary coil. The converter has a DC input and a capacitor bank, having a pair of capacitors, is connected across the DC input. A switch is associated with each primary coil. A gate drive feedback module outputs a pulse width modulated signal to drive either the first or second primary coil. A gate drive switch has as an input the pulse width modulated signal and outputs to the first second switch. A pulse steering logic module determines which of the first or second capacitors has a higher voltage and controls the gate drive switch to direct the pulse width modulated signal in response thereto.

摘要： A motor bypass is controlled by a digital signal processor (DSP) with embedded control software that allows fault detection and annunciation, serial communications between both a variable frequency drive (VFD) and a bypass controller and the bypass controller and a host computer. The use of the DSP and embedded control software further allows for contactor coil control to provide fault tolerant operation as well as fault condition detection and annunciation to the user.
