Key applications
- Solar array power conditioning
In space systems, solar arrays are crucial for providing electrical power to the satellite. The energy captured by the solar arrays needs to be conditioned and regulated to match the voltage and current requirements of the satellite's systems. A half-bridge DC-DC converter, with its ability to efficiently step-up or step-down voltage levels, can be used for maximum power point tracking, voltage regulation, and overall power conditioning. This ensures that the power generated by the solar arrays is optimally utilized by the satellite's systems. - Electric propulsion systems
Electric propulsion systems are gaining prominence in satellite propulsion due to their efficiency and long-term operation capabilities. These systems require precise control of the power supplied to the electric thrusters. A half-bridge DC-DC converter can be used to step up the voltage from the satellite's power bus to the levels required by the electric thrusters. Additionally, the converter can provide the necessary isolation and regulation to ensure the electric propulsion system operates reliably and efficiently. - Payload power management
Satellite payloads encompass a wide range of instruments and devices, each with distinct power requirements. A half-bridge DC-DC converter can play a vital role in regulating and distributing power to these payloads. By providing multiple output voltage levels and efficient power conversion, the converter ensures that each payload subsystem receives the precise and stable power it needs for optimal performance.
