Multiple cores used to simulate a variable volt-second saturable transformer for application in self-oscillating inverters.
Square-loop cores with multiple windings used in single transformer package for application in self-oscillating inverters
Variable frequency transistor inverters use multiple core transformers
Magnetic-coupled multivibrators containing two or more square-loop cores with multiple windings in a single transformer package, provide indirect frequency control and improved operational characteristics. This multivibrator can be used for power oscillators, nonlinear magnetic circuitry and telemetry circuits.
