ABSTRACT:
A power supply circuit for generating true sine wave signals by regulating the average value of the signal, whereby the RMS value of the signal is regulated accordingly. By monitoring the circuit through the load, represented by a monitored voltage value, a feedback network is coupled to a variable resistor in conjunction with other circuitry to maintain a constant voltage ratio to the power transformer assuring a properly shaped wave at a larger or smaller variation.
