Abstract

A high-efficiency low-profile driving amplifier for smart actuators is essential for portable actuator devices. In this paper, an optimized design of a half-bridge switching circuit to drive smart actuators is described. A genetic algorithm, which is well suited for solving the discrete optimization problem, is applied to the traditional circuit design to make it smaller and more efficient. The calculation of the power dissipation of the MOSFET is a prerequisite for obtaining realistic designs. The results of the optimization procedure are summarized.
