TIDA-00229 Self or Dual-Powered Supply for Protection Relay, MCCBs & ACBs Ref Design | TI.com
TIDA-00229: This power supply solution for Protection Relays & MCCBs handles both the current input from a Current Transformer (CT) or input from an Auxillary (Aux) source. The "self-powered" capability comes from being able to harness the power available in the grid through the CT. The flexibility of this solution's "dual-power" input comes from the ability to also handle the Aux input - which is often a battery source.
Low-Power, Low-Noise Analog Front End Design for Circuit Breakers (ACB/MCCB-ETU)
TIDA-00128: This reference design is intended for use in molded case circuit breakers (MCCB) electronic trip units. The op amp based design acts as current monitoring for over-current earth fault relays. Utilizing a low cost op amp, this design provides a pick-up (A) accuracy ±10 % and time delay (s) accuracy 0 to -20%. Additionally, this design takes harsh environment conditions in mind with features such as ambient insensitivity from -10 to 70°C and high electromagnetic immunity. Finally the analog front end of this design seemlessly interfaces to TI MSP430 MCU for quicker evaluation and faster time-to-market.
PMP5761 PFC Boost LLC Resonant Half-bridge 24V@3.5A | TI.com
PMP5761: PMP5761 is designed for hybrid filber/coax system with nominal 40VAC-90VAC input and generate a 24V/3.5A output. A cascade PFC and LLC-SRC two stage system is applied in this design to guarantee high power factor is achieved in nominal input range. Transition mode PFC controller UCC28051 and resonant converter controller UCC25600 are applied to PFC and LLC-SRC, respectively. With PFC output set to 300V, PMP5761 is able to keep out in regulation with input up to 200VAC. 80% converter efficiency is achieved at 40VAC and 87% converter efficiency is achieved at 115VAC.
