Martins Electronic Devices & Instruments manufactures SMPS Type Voltage Static Stabilizer. Martins Electronic Devices & Instruments supplies various types of H.F Generator, U.V. Tester, Solid State Data Logger, etc. The SMPS Type Voltage Static Stabilizer is designed for mains voltage [AC input and AC output]. The power stage is an IGBT chopper control. The chopping frequency is around 20 KHz which ensure absolutely silent operation and pure sinewave output [no waveform distortion]. The control section is based on dsPIC controller which ensures quick correction of output which is not possible in conventional relay type stabilizer or servo controlled stabilizers. The circuit is having LCD display which will show all parameters like: input voltage, output voltage, connected load, etc. The transformer size will be only 1/4th of the output power. For 2KVA stabilizer transformer size will be that of 500 VA.
