Abstract
Silicon controlled rectifiers may be used for the generation of high-power audio frequencies up to at least 10kc/s. The use of these components in the place of transistors can result in considerable savings in equipment size and weight. Also, by reducing the number of components used, an improvement in reliability should be realized.The generator described here employs a series self-quenching circuit instead of the better-known parallel inverter. A general analysis of the circuit is given, and expressions required for the design of a generator are derived. This theory is applied to a circuit required to deliver approximately 2kW into a near-resistive load at a frequency of 10kc/s. Results obtained from such a generator are given, and some practical difficulties encountered in the construction of the circuit are outlined.
