Qualified pulse magnetics designed for ultra-low core loss, superior voltage isolation, and long-term operating stability under harsh electrical environments.
Pulse transformers serve as critical nexus components in modern power electronics, responsible for transferring rectangular voltage pulses with rapid rise times while ensuring galvanic isolation between control circuits and high-voltage power stages. In the Australian energy and mining sectors, operating conditions demand stringent adherence to parameters like pulse width integrity, low leakage inductance ($L_k$), and high volt-second product ($E \cdot t$).
When selecting pulse transformers for deployment across Australian industrial plants—ranging from the Pilbara iron ore operations in Western Australia to utility-scale solar installations in Queensland—engineers must prioritize thermal margins, interwinding capacitance ($C_{ww}$), and insulation safety standard compliance under IEC 61800-5-1 and AS/NZS 61000 standards.
Our custom and standard pulse transformer topologies utilize ultra-low loss MnZn ferrite cores, planar magnetics architectures, and specialized triple-insulated wires (TIW) to guarantee immunity against dv/dt transients exceeding 100 V/ns generated by fast-switching SiC and GaN power semiconductors.

As Australia accelerates its transition toward 100% renewable energy penetration and local advanced manufacturing, magnetic design requirements are undergoing structural shifts.
Australian power converter manufacturers are aggressively switching from traditional Silicon IGBTs to Silicon Carbide (SiC) and Gallium Nitride (GaN) devices. This shift requires pulse gate transformers capable of handling high $dv/dt$ rates (exceeding 100 kV/μs) without parasitic triggering.
Equipment deployed in inland Australia faces ambient temperatures surging past +45°C inside outdoor enclosures. Pulse transformers must utilize Class H (180°C) or Class R (220°C) insulation materials to ensure 20+ year operating lifespans under continuous thermal stress.
With AEMO enforcing strict harmonic compliance guidelines for grid connections, multi-pulse rectifier systems (12-pulse, 18-pulse, 24-pulse) are increasingly specified to reduce Total Harmonic Distortion (THD) below 5% at point of common coupling.
