Description

The e-STARTER demonstration board represents

an innovative solution patented by

STMicroelectronics to reduce the power losses

caused by positive temperature coefficient (PTC)

resistors in compressor starter circuits.

The solution features an ACST6 AC switch device

which is used to turn off the PTC current after

motor start-up. It should be noted that the

traditional PTC is still used in the electronic

starter circuit, as it increases the safety of the

circuit in cases of AC switch short-circuit or diode

mode failure (ref. EN60335-1).

The design allows the starter standby losses to be

reduced from (typ) 2.5 W to 380 mW for 230 V

applications, or 2.5 W to 40 mW for 100 V

applications.

Because this board is not a “plug and play”

solution, prior to using the board with a

compressor the PTC behavior must be checked

(especially VPTC1 & VPTC2 levels), and different

R4 resistor value may be required.
