Hi All,
After reading John Stevensons reply re Inverters, I looked up the R.S. catalogue and was surprised at how low the price actually is, especially as these things seem to command a price of at least double this on ebay. Can anyone tell me the principal of operation of the output stages in these devices. The 3 phase generator is no problem, but I wondered if the output stage uses power transistors as switches, and leaves the coil inductance to give an approximate sine wave, or whether these transistors are actually used as linear amplifiers ?.
Best regards,
Tom.
