Product Overview

The STEVAL-ISF003V1 is an evaluation board allows low standby losses power front-end with inrush current-limitation. This evaluation board allows limitation of the inrush current charging a DC bus capacitor to comply with standard IEC 61000-3-3. This inrush current limitation is based on a soft-start procedure of the mixed bridge diodes and SCRs rectifier using progressive phase control at board start-up. This solution drastically reduces standby losses as DC bus can be totally disconnected from AC mains when it does not have to operate. DC bus deactivation is simply achieved by turning off SCRs without requiring an additional relay to open circuit in standby. The steady state losses are also reduced.
  • Electronic solution without an inrush current limiter resistor, bulky bypass electromechanical relay
  • DC bus disconnection at standby to reduce losses below 0.3W
  • Inrush current compliance with IEC61000-3-3
  • Operation allowed with PFC (continuous or discontinuous)
  • Compliant with EN 55015, IEC 61000-4-11
  • Criteria A at 4 kV IEC 61000-4-5 and at 4 kV IEC 61000-4-4
