| Abstract: | A low voltage ripple interleaved parallel Boost converter for a pulsed laser driver is designed, and a multi-channel interleaved parallel structure is adopted to effectively reduce the output voltage ripple under heavy load. The theoretical no-load maximum output voltage is 120 V, the maximum output power is 119.2 W, and the output voltage ripple under heavy load is less than 5 mV. The effects of the number of parallel channels and the time interval of each channel inductance discharge on the output voltage ripple are studied in detail. In addition, the method for estimating the ripple of multi-channel output voltage based on the output parameters of a single-channel Boost converter is summarized, which can provide a basis for determining the number of parallel channels of the interleaved parallel Boost converter. |
