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:
|

|
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.
