2. ABSTRACT
• This project presents input-series–output parallel (ISOP) configuration for single-
phase front-end buck rectifiers (BRs).
• The configuration is especially suitable for traction applications, where the
complete rectification system needs to withstand high ac voltages and supply
medium-power loads.
• The primary rectification module of the proposed configuration is based on pulse
width-modulated BR (current source inverter topology).
• The desired isolation, mandatory for ISOP connection, is provided at the dc stage
through a medium frequency/ high-frequency transformer.
• Equal power sharing by modules is achieved from the ac side through input
voltage and current sharing.
• The proposed control scheme is configured using two loops. While the outer
loop regulates the output dc voltage and active wave shaping of the source
current, the inner loop ensures stable voltage sharing
