The SiCMag family of power supplies corresponds to a range of generators for induction heating applications covering power levels from 12,5 to 800 kW and frequencies up to 400 kHz in two ranges 5 to 50 kHz and 20 to 400 kHz.
SiCMag generators are based on the ultimate power electronics technologies as Silicon Carbide (SiC) MOS Transistors, advanced DC link using antiferroelectric capacitors, ultrafast high isolation circuitry and advanced transistor driving circuits and fully digital controller all integrated in a PCB, allowing inverter efficiencies up to 99% @400 kHz and consequently very small and compact chillers.
Due to the wide frequency range of SiCMag generators many induction heating applications can be covered with the same generator. Also, the power output of SiCMag generators can be configured as single-power port or independent multi-power port output, allowing different applications with different power levels, different frequencies and also simultaneous frequency applications
Power upgrading in SiCMag generators is a very simple operation, if the safety and input mains sections is prepared for, by just adding more power modules in the SiCMag cabinet.
SiCMag generator family is housed in three different types of cabinets.
- The SiCMag….L is housed in a standard cabinet and ranges powers from 100 to 800 kW while
- the SiCMag….M is thought for its installation in a wall for applications with limited space and
- the SiCMag….S is thought for portable applications.
In combination with SiCMag generators, SiCtech offers standard as well as custom design heating stations integrating in a, up to 10 m., separate cabinet high efficient output transformer, resonant capacitors and if needed a matching transformer, that could be placed near the heating workpiece.
The Main Advantages of SiCtech Induction Technology
- Wide Range of applications with the same generator.
- Extremely high efficiency inclusive at frequencies as high as 400 kHz.
- Very small size and weight.
- Very high robustness due to the use of SiC MOS Transistors.
- Very easy use of the generator due to the use of advanced cyber-physical algorithms that auto-adjust the generator depending on the required heating process.
The SiCMag Family Features & Subsystems
SiCMag generators are divided in two frequency classes, 5-100 kHz and 20-400 kHz, covering the first class, power levels up to 800 kW and the HF frequency class covers powers up to 400 kW. The supply voltage is 400-480 VAC and the system is water-cooled. Depending on the power level, standard SiCMag generators include a SiCtech or a Siemens PLC with communication via industrial busses like Profinet, Modbus, Ethernet etc.
The SiCMag MF frequency class generators is based in 50 kHz SiC power modules, and the SiCMag HF frequency class in 400 kHz SiC power modules, including the modules, in both cases, the same controller, and a PCB including all the features needed in an induction heating application.
In combination with SiCMag generators, SiCtech offers standard as well as custom design heating stations integrating in a, up to 15 m., separate cabinet highly efficient output transformer, resonant capacitors and if needed a matching transformer, that could be placed near the heating workpiece. Standard heating stations cover a range of frequencies between 5 and 50 kHz and 20 to 400 kHz for heating any conductive material as iron, copper, aluminium stainless steel, etc
A highly interactive and comprehensible HMI based on Siemens PLC 1200 or SiCtech PLC, guides the user in any interaction with the generator as the starting up, the resonant frequency selection by autotuning, the matching of the load etc. and provides information on the status and working conditions of the generator at any time.
