OverviewThe TPS-BM57050KTIF is a three-phase bidirectional AC-DC power module designed for high-power energy conversion without neutral line current. It uses soft-switching technology to reduce switching losses and improve reliability. The module delivers up to 50 kW with high efficiency (96% AC→DC, 95% DC→AC), a high power factor (PF >0.99) and low THDi (<5%), making it suitable for demanding industrial test benches and energy-recycling systems. It supports 380/400/415 VAC rated inputs, a 570 VDC bus output, modular expansion and forced air cooling. Integrated CAN and RS485 communications enable monitoring and control integration.
