STEVAL-ISA007V1 high power 3 phase auxiliary power supply evaluation board based on L5991 and emitter switched bipolar transistor STC08DE150HV. A dedicated reference design with ESBT has been developed, featuring the high power wide input range requirement of a highly demanding industrial market. The maximum output power is 150W. Generally, the necessity to handle both high output power and wide input voltage leads to the design of a fly back stage working in mixed operation mode: continuous and discontinuous. With the adoption of the PWM L5991, the converter is able to operate in mixed mode. For higher power levels with a switching frequency close to 90KHz, the converter operates in continuous current mode, while in stand by and for power levels lower than 25W, the converter works in discontinuous current mode at a switching frequency of about 35KHz. The STC08DE150HV, in conjunction with the PWM L5991, perfectly fulfills the requirements and brings high efficiency to the system.
  • Three phase 150W auxiliary dual output SMPS
  • Input voltage 400Vac +/- 20%
  • Output voltage 1 is 24V, 6.25A at 90KHz
  • Output voltage 2 5V, 0.075A at 90KHz
  • Auxiliary output voltage 15V, 0.01A
  • Maximum output power 150W
  • Efficiency 85%
  • Switching frequency 90KHz
  • Standby switching frequency 35KHz
  • Feedback: secondary regulation
