SPEED CONTROL OF FHP SYNCHRONOUS MOTOR USING THREE PHASE VSI INVERTER. |
| |||||||||
The variable frequency drive for synchronous motor, has advantage over variable voltage such as, (1) to vary speed in stepless manner(2) to maintain constant torque/power(3) to run motor on slower/ higher speed than ratedThe V.S.I. (voltage source inverter) drive is one methodto obtain the variable frequency voltage to control speed/torque of Synchronous motor |
This kit is designed to study low capacity SCRparallel inverter input -output characteristics.The kit consists inverter transformer, 2 SCRs, one inductor, one commutation capacitor, onedc ammeter, firing circuit and provision forconnection of resistive load and on delay circuit. |
This method to have a net output with reducedharmonic current, output voltage from two(or more) inverters can be combined by meansof two identical transformers. The essentialcondition of this method is that the outputvoltage waveforms from the inverters must besame, but phase shifted fromeach other |
MACMURRAY FULL(OR HALF) BRIDGE INVERTER |
The kit is designed to studyMacmurray half/fullbridge inverter characteristics. The kit consists8 SCRs, two inductor, two commutationcapacitor, four diodes, firing circuit and load inform of wire wound resistor. The power sourceis inbuilt & operates at 220 Vac line. |
In series inverter, the resonating elements L-C
(commutating elements in thyristor inverter)
are introduced in series with the load. This
constitutes a series resonate circuit, where the
load (R) is purely resistive. This type of inverter
produce an approximately sinusoidal
waveform at resonating frequency
In series inverter, the resonating elements L-C(commutating elements in thyristor inverter)are introduced in series with the load. Thisconstitutes a series resonate circuit, where theload (R) is purely resistive. This type of inverterproduce an approximately sinusoidalwaveform at resonating frequency. Because ofIGBT (instead of SCRs) does not suffer fromthe problem 'commutation' , hence the maximumfrequency operation can be obtained. |
The kit is designed to study low capacity SCR
bridge inverter input - output characteristics.
The kit consists 4 SCRs, two inductor, four
commutation capacitor, one dc ammeter, firing
circuit and provision for connection of resistive
load in form of wire wound resistors.
The power source is inbuilt with the kit fully
regulated and overload/overcurrent protected.
