High-frequency power inverters utilize high-speed switching at frequencies significantly higher than the standard 50/60 Hz grid frequency. This article provides an overview of high-frequency inverter topologies, design considerations, applications, and advantages versus traditional lower frequency inverters.
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.
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).
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).
