Power Electronics
High-efficiency AC-DC, DC-DC, and solid-state transfer systems. AISPL power topologies focus on zero-cross soft-switching, active harmonic reduction, and ultra-fast dual-source phase transition without relay contact arcing.
Core Engineering Principles
Zero-Cross Soft Switching
Microcontroller synchronized firing of solid-state relays precisely at AC zero crossing to eliminate inrush currents and EMF transients.
Active Phase Shifting (DSAPS)
Patented phase-shifting architecture providing seamless transfer between primary and secondary AC supplies within 10ms.
Leakage Current Mitigation
High-sensitivity residual current detection and active neutral balancing for human and equipment safety.
System Architecture Flow
End-to-end signal processing and control path engineered for Power Electronics.
Mains Sensing & Waveform Analysis
High-speed true RMS sampling of AC voltage, frequency, and harmonic distortion.
Synchronized Zero-Crossing Detection
Sub-millisecond optical isolation triggering for switching semiconductors.
Solid-State Commutation Stage
Dual-triac / back-to-back MOSFET switching with zero mechanical arcing.
Output Power Conditioning
Multi-stage LC filtering suppressing high-frequency harmonics.
