Programmable Power Electronic Controller

PPEC (Programmable Power Electronics Controller) is a digital power control core developed by Wuhan-based Senmu Leishi, a national high-tech enterprise focused on R&D, manufacturing, and sales of power electronics solutions . The product line represents what the company calls the first "standardized digital power controller" in China, built on more than a decade of proprietary algorithm development .

The core value proposition centers on code-free development: engineers use the PPEC Workbench graphical programming platform instead of writing C code, with menu-driven configuration, online parameter tuning, and virtual instrument displays to accelerate power supply design . Hardware-wise, PPEC integrates the digital control circuits needed for common topologies into highly compact chips, aiming to reduce both talent requirements and time-to-market for power electronics firms .

As of 2023, the PPEC series had three commercial chips: the PPEC-86CA3A phase-shifted full-bridge controller, the PPEC-86CA3H LC series resonant controller for high-voltage chargers, and the PPEC-86CA3B LLC resonant converter chip targeting high-efficiency, high-power DC/DC applications in data centers, EVs, and medical equipment . By 2026, Senmu Leishi had extended PPEC-based power systems into frontier domains including tokamak core power supplies for controlled nuclear fusion, particle accelerator power for nuclear medicine, and specialized microwave power for synthetic diamond growth .
