Traditionally, most testing labs used variable transformer or Variac to change the voltage (ex: 100~520V) and motor generator set to change the frequency )ex: 50Hz, 60Hz, 400Hz). Nowadays, many testing applications require higher precision control and need to regulate the voltage for their testing unit. Traditional way are too noisy, not easy to use in indoor, harmonic noise, not easy to adjust and efficiency is low. The programmable AC power supplies are also too expensive for this type of applications. We are going to present a better way of static type power source with high cost performance value. Also, will go into explaining the difference between designs, advantages/disadvantages and suitable applications for both ways.
