A Dual-Output Hybrid-Boost (DOHB) Converter for 37.5 V/150 V with Continuous Current Delivery and Switching Charge-Recycling

초록

This paper presents a dual-output hybrid boost (DOHB) converter that generates 37.5 V and 150 V from a 2.5–5 V input. The first stage achieves a high VCR at moderate duty, lowering both the DC level and ripple of IL to minimize conduction losses. The second stage supplies VO2 = 4×VO1 with continuous current delivery, achieving <5mV ripple at VIN = 3.4V and VO2 = 150V, while switching charge-recycling halves node switching loss.
