1-kV switching power supply
Designing a high-voltage switching power supply that can produce a sustained arc can be challenging. This compact and efficient design delivers 1 kV at 20W and can withstand a continuous arcing, or short-circuit, condition (Figure 1). It uses standard, commercially available components. R1 sets the LTC1871 switching-regulator controller for a nominal operating frequency of 120 kHz.
