GCT's system architectures allow for flexibility when challenged with the multiple power sources of today's markets. Converting power from a wall plug or renewable energy source is a critical part of the power system. GCT can provide an off-the-shelf power supply or develop a custom power supply when further optimization is required. Our system design approach ensures that the system monitors the power source for multiple limits and maximum power point tracking. Continuous development and reuse of our various input circuit blocks, combined with our proven convertors and chargers, allow customization of the overall system while maintaining superior quality standards.

User Interfaces: Multiple Standard Interfaces and Options for Customized I/O's

GCT utilizes our extensive database of successful design building blocks to create electrical hardware that meets customer-specific requirements while adhering to the necessary industry standards. Along with customized I/O's, GCT's design can incorporate multiple interfaces including USB, Ethernet, CAN, I2C, SPI and WiFi to enable intelligent communication with the system components as well as external software.

Convertors: Proven Designs Optimized to Maximize System Efficiency

GCT understands that the key to a great convertor is efficiency. GCT has a vast library of design blocks for AC/DC, DC/DC and DC/AC. These are the first blocks that will suffer in a power system due to heat and voltage stress, so we use existing, proven blocks or develop a new block to optimize the performance of each power system. By providing higher efficiency and component stress validation, GCT delivers a power block that is smaller and less expensive with lower temperature emissions and improved reliability.
