STEVAL-IHT008V1 Data brief Low standby loss front-end with inrush current limitation and insulated AC switch control Features Fully electronic solution without the need for an inrush current limiter resistor and bulky by-pass electromechanical relay DC bus disconnection at standby to reduce loss below 0.3 W Inrush current compliant with IEC61000-3-3 Operation allowed with PFC (continuous or discontinuous) EN 55015, IEC 61000-4-11 compliant Criteria A 2 kV IEC 61000-4-5 and 4 kV IEC 61000-4-4 Insulated control of AC switches used to drive AC loads for residential appliances RoHS compliant Description The STEVAL-IHT008V1 evaluation board limits the inrush current charging a DC bus capacitor so that it is compliant with the IEC 61000-3-3 standard. This inrush current is based on a soft-start procedure for the rectifier bridge achieved with a T1635T-8FP Triac added in series with the mains line, which is controlled by the STM8S103K3 microcontroller through progressive phase-control during the startup phase. This solution drastically reduces standby losses as the DC bus can be totally disconnected from the AC mains when it is not required. The DC bus is easily turned off by turning off the series Triac, without needing an additional relay to open the circuit in standby. Product summary Steady-state losses are also reduced because NTC resistors, traditionally used to limit inrush current, are not required nor are the corresponding relays to bypass STEVAL-IHT008V1 STEVAL- them. evaluation board IHT008V1 This board also demonstrates that AC loads can be driven with an easy-design STEVAL-IHT008V1 evaluation board STSW-IHT008 isolated solution using the same power supply for the whole system and some opto- firmware transistors to control the ACST210-8FP, ACS108-8SN and Z0109MUF AC switches.
