Abstract
The invention provides an active control drive power supply for a shape memory alloy. The drive power supply uses a closed loop control system consisting of a current stabilized regulating controller, a gate turn-off thyristor and a current sensor; the current which is output to the shape memory alloy is controlled via continuously sampling weak voltage signals which are output by a digital-modulus converting card at a computer end so that the voltage signals at the computer end are in one-to-one correspondence with the output current intensity. Each case of the drive power supply is provided with three passages which can simultaneously and independently drive three shape memory alloy wires; in order to enable the power supply to adapt to an inductive load, each passage is provided with a capacitance and resistance absorbing module to prevent the gate turn-off thyristor from being punctured by the high voltage generated by the inductive load. The shape memory alloy active control drive power supply is simple in structure, convenient and fast in use, high in drive power, convenient in operation and wide in regulating range.
