Multiplied SEPIC Constant Current Capacitor Charger (15Vin to 400V/@ 80mA) Reference Design

Overview

TopologySEPIC Buck-Boost Topology
Input voltage15 V
Output 1400 V / 0.08 A
Output 2420 V / 0.08 A
IC revisionB

Description

A SEPIC converter is used to charge a load capacitor (up to 15000uF) up to 400V/420V (selectable). The input voltage range is 15V +/-10% and the constant output charging current 80mA. The multiplied SEPIC topology has several advantages compared to Boost + charge pump mainly thanks to reduce peak and RMS currents in the multiplier of the SEPIC.

Features

Remarks: Schematic and BOM is added with Test procedure PDF

huge ratio possible by multiplied single-stage SEPIC (15Vin to 420Vout)No spikes on switch-nodes compared to flyback solutionGood efficiency curve between 50Vout and 420Vout in the range of 80% to 87%Two active loops: CV and CC avoid overvoltage in case of load disconnection
