Switched-Mode Power Supplies Shrink in Size:
1/ Employ piezoelectric transformers. They enable high-frequency power converters to achieve lightness, smallness, thinness, and high power density. Piezoelectric transformers utilize the unique "voltage-vibration" and "vibration-voltage" conversion properties of piezoelectric ceramic materials to transmit energy, with their equivalent circuit resembling a series and parallel resonant circuit.
2. High-frequency: To achieve high power density in power sources, we increase the operating frequency of the PWM converter, thereby reducing the size and weight of the energy storage components in the circuit.
3. Implementing new capacitors. To reduce the size or weight of power electronic devices, it is necessary to improve capacitor performance, increase energy density, and develop new capacitors suitable for power electronics and power supply systems. These capacitors should have a large capacitance, low equivalent series resistance (ESR), and a small size. 36V aviation power supply, 400HZ frequency conversion power supply, 115/200V power supply, 27V DC power supply, 400HZ power supply, aviation power supply
