Thyristor Commutation in DC Choppers - A Comparative Study
TL;DR: The typical dc helicopter motor controller consists of two thyristors, two or three diode rectifiers, a commutator, and one or more commutating inductances.

A Two-Quadrant Transistor Chopper for an Electric Vehicle Drive
TL;DR: In this paper, a two-quadrant dc-dc transistor converter capable of delivering 400 A motoring current and of generating 200 A braking current is described, and the interaction of the snubber networks for the motoring and braking transistors is described and design considerations presented.

Pulse control of D-C and A-C motors by silicon-controlled rectifiers
TL;DR: In this paper, the silicon-controlled rectifier (SCR) can be turned off by means of capacitor discharge pulses and, therefore, it can be used not only to switch on heavy currents, but also to switch them off.

Pulse-Width Modulation DC Motor Control
TL;DR: In this paper, a dc series motor is used as a traction drive for vehicles, and it is desirable to control the voltage to the motor to fit the various torque requirements of grades, speed, and load.

Silicon-controlled rectifier D-C to D-C power converters
TL;DR: In this article, the operation of a d-c chopper circuit using a silicon-controlled rectifier (SCR) is analyzed, and the specific circuits employed a variable repetition frequency to control load voltage, but the modifications necessary for operation at a fixed frequency with variable “on” time are also mentioned.
