Abstract
A magamp circuit including a saturable reactor for regulating the output energy delivered to a load and having a protective circuit for restricting energy flow to the load in the event of occurrence of a short-circuit at the load. Output energy fluctuations are reduced through the use of a non-linear feed forward response circuit. A circuit which compensates for an unwanted voltage reset applied to the saturable reactor due to reverse current leakage or reverse recovery energy of a protective diode is also provided.
Claims17
A circuit for maintaining an output signal at a given level comprising:
- an input receiving a signal of a given frequency;
- an output
- a saturable reactor coupled between said input and output and having a variable impedance for controlling the level of the signal delivered to a load coupled to the output;
- a differential amplifier for controlling the impedance of said saturable reactor;
- and
- a feedback circuit monitoring a level of an output signal across the load for applying a control signal to said differential amplifier;
- said differential amplifier having a first output coupled to the saturable reactor for increasing the impedance of the saturable reactor when the feedback circuit determines that the output level is greater than a threshold and a second output coupled to the saturable reactor for reducing the impedance of the saturable reactor when the output level is below said threshold.
