Description
Instead of a thyristor bridge, a "PWM converter + IGBT chopper" chain works here, performing AC/DC and DC/DC conversion. The power factor exceeds 0.99, current harmonics comply with IEEE 519 with THDi below 3 %, and DC ripple does not exceed 5 % of the rms value. The electrolyzer in current-stabilization mode is loaded less, and the project does without reactive power compensators and harmonic filters, which would have to be included in the budget with a thyristor rectifier. For large electrolyzer parks the modules are placed in stackable containers and power is increased vertically on a minimal footprint.
How to choose
The type is selected by the stack current and power. The range is: Type 10 at 650 kW and 1 kA, Type 11 at 1800 kW and 3.75 kA, Type 11+ at 3000 kW and 4 kA, Type 12 at 1800 kW and 7.5 kA, Type 12+ at 3000 kW and 8 kA, Type 22 at 3600 kW and 7.5 kA, Type 22+ at 6000 kW and 8 kA, Type 23+ at 6000 kW and 12 kA. Power and current are built up by the number of PWM converter and IGBT chopper blocks, so for a 7.5 kA stack take Type 12 or Type 22 depending on the required power. If the stack voltage is above 720 V, a "+" model delivering up to 1000 V DC is needed.

FAQ
What input voltage does the TMHyREC require?
Type 10, 11, 12 and 22 are connected to 420, 440 or 500 V AC, the "+" models to 690 V AC, and the mains frequency tolerance of 50/60 Hz is ±2 %.
What DC output voltage does the TMHyREC give?
Basic models regulate the output within 50–720 V DC, the "+" models within 50–1000 V DC, which suits stacks with a higher working voltage.
What installation conditions does the TMHyREC need?
The rectifier is installed indoors only, at a temperature of 5–40 °C and at an altitude up to 1000 m. The power section is cooled by water and the other parts by air, so a cooling water circuit must be brought to the cabinets.
What else can be taken for a hydrogen project together with the rectifier?
The same manufacturer supplies power supply systems from 300 kV, compressor drives (in the low-voltage class this is, for example, the TMdrive-10e2 at 460, 575 or 690 V), Solar Ware Ninja solar inverters at 800–880 kW and energy management systems.
