设计一种能够产生连续电弧的高压开关电源可能是具有挑战性的。这种小巧高效的开关电源在输出功率为20W 时可输出1kV 电压,并能耐受连续电弧(即短路)(图1)。它使用标准的市售元件。使用 R_1将开关稳压控制器LTC1871设定在120kHz 的额定工作频率。该电路像间断式回扫电路一样工作,在 C_1上产生333V 电压。二极管/电容器电荷泵倍增器把该 Designing a high-voltage switching power supply capable of generating continuous arcing can be challenging. This compact, highly efficient switching power supply delivers 1kV at 20W and withstands continuous arcs (shorts) (Figure 1). It uses standard commercially available components. Use R_1 to set the switching regulator controller LTC1871 to 120kHz nominal operating frequency. The circuit works like a flyback flyback circuit, producing 333V on C_1. The diode / capacitor charge pump multiplier puts this
