This article provides an overview of high-frequency inverter topologies, design considerations, applications, and advantages versus traditional lower frequency inverters.
What are high frequency inverter circuits used for?
High frequency inverter circuits can be used in many applications where efficient power is needed. For instance, they can be used to power a wide variety of electrical devices, including computer servers, medical equipment, air conditioning systems, and even large scale solar energy systems.
What are common high-frequency inverter circuit configurations?
Common high-frequency inverter circuit configurations include: Key design factors for high-frequency inverters: Switching frequency – Higher frequency allows smaller filter components but increases losses. Optimize based on tradeoffs. Filter components – Smaller inductors and capacitors possible at high frequencies. Balance size versus performance.
Which power supply topologies are suitable for a high frequency inverter?
The power supply topologies suitable for the High-Frequency Inverter includes push-pull, half-bridge and the full-bridge converter as the core operation occurs in both the quadrants, thereby, increasing the power handling capability to twice of that of the converters operating in single quadrant (forward and flyback converter).
How does a high frequency inverter work?
High-Frequency Inverter Technology The full bridge (S1...S4) generates a high-frequency square-wave signal with 40 – 50 kHz, which is transmitted via the HF transformer (Tr1). The bridge rectifiers (D1...D4) convert the square-wave signal back to DC voltage and store it in the intermediate circuit (L1+C2).
What are the components of a high frequency inverter circuit?
The most important component of a high frequency inverter circuit is the transformer. This component is responsible for converting the DC current into AC power. Depending on the application, different types of transformers can be used, such as pulse width modulated (PWM), full wave, half wave, and peak-to-peak.
