Energy systems are becoming more electrified, decentralized, and power-dense. Yet many installations still rely on several separate converters, interfaces, and control stages. This increases hardware cost, cabinet volume, installation work, maintenance exposure, and system-level failure points.
Cupulse Interfaces is developing an integrated bidirectional converter architecture that combines multiple power-conversion functions into a compact platform. The objective is simple: fewer system blocks, fewer interfaces, lower total cost, and a clearer route to scalable energy infrastructure.
The company is currently moving from prototype development toward technical validation and pilot dialogue, targeting electrified infrastructure applications where converter complexity, integration cost, and scalability remain major industry challenges.
Current simulation results indicate high-efficiency performance characteristics while enabling multiport interconnection capability, where a single converter platform is designed to manage up to six interconnected systems simultaneously. Through parallel coupling, the architecture is intended to support scalable expansion across increasingly complex power environments.
Compact converter topology • Multiport energy flow • Designed for scalable grid, storage, generation, and load integration
Core converter architecture is undergoing novelty assessment prior to patent application.
Cupulse Interfaces targets applications where several energy flows must be connected through one reliable platform: battery storage, renewable generation, industrial loads, EV charging, backup power, microgrids, and smart grid interfaces.

A simpler converter architecture can reduce material intensity, power losses, cabinet volume, and maintenance requirements. For Cupulse Interfaces, sustainability is a direct engineering outcome of lower system complexity.
We are looking for conversations with investors, utilities, industrial partners, and pilot customers who want to simplify power conversion architecture.
