10 A Pulse amplifier embedded in system board. Power transistor is at top; capacitor supply is to right.

Power pulse amplifiers are used in pyrotechnic pulse generators, laser drivers, medical equipment, and other test and measurement instruments (such as curve tracers) requiring pulses of high power or a wide current or voltage range. This pulse amplifier offering includes a tutorial design tech report, with specific design explanations of how two power pulse amplifiers were designed. Sections include:

	Pulse amplifier system design
	Pulse amplifier efficiency
	4 A PG circuit design
	10 A PG circuit design
	Ground and load fault detection
	Output connector sense circuit
	Dynamic response and load cable model; includes MathCAD root locus programs
	Power output stage design considerations
	Component selection

Power pulse-amplifier theory covers load characteristics, amplifier isolation, precision 4-wire techniques, safety issues, noise and grounding considerations, high power-pulse output transistors, frequency and transient response, feedback control theory, and other power-pulse-specific design concepts. These general principles are illustrated in concrete design examples of two basic designs, as described below.
