Transient response of controlled rectifier circuits

Transients in circuits supplied by controlled rectifiers using gas or mercury-vapor-filled electron tubes are found analytically by an extended superposition method. Loads containing resistance, inductance, and a counter electromotive force are studied, and results are obtained for both rectification and inversion. Examples are based on the half-wave biphase rectifier, while the appendix contains an analysis of a p-phase rectifier. The assumptions include constant-circuit parameters, a fixed firing angle during transients, continuous load current, and no-leakage reactance in the supply transformer.
