Abstract
A power supply circuit for supplying a load, which may be a SMA component or a piezoelectric component, may use short high-voltage pulses to achieve fast heating of the load and, in order to comply with functional requirements, the SMA or piezoelectric component should not be supplied by connecting it directly to an electric line at a relatively high voltage. It is also disclosed an actuator comprising a power supply circuit of this disclosure and at least one load, comprising at least one smart materials chosen between a piezoelectric device and a a shape memory alloy (SMA) component, and a method of supplying a load comprising the steps of: connecting the AC to DC voltage converter of the power supply circuit to the AC mains by closing the input switch for charging a tank capacitor of the converter and, at the same time, opening the output switch for disconnecting the load from the tank capacitor: disconnecting the AC to DC voltage converter of the power supply circuit from the AC mains by opening the input switch and, at the same time, closing the output switch to supply the load by discharging the tank capacitor.
