STEVAL- IHT003V1演示板是基于ACST6压缩机起动电路的低损耗的电子入门演示板。便于减少所造成的正温度系数在压缩机起动电路（PTC）电阻的电力损失。是意法半导体公司电子入门演示板专利的创新解决方案。The e-STARTER demonstration board represents an innovative solution patented bySTMicroelectronics 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.
