PMP23630
概述
This reference design is a two-stage, high-efficiency, 30kW power supply with a high voltage DC (HVDC) output. The first stage is a three-level flying capacitor power factor correction (PFC) converter running off of a three-phase input source. The PFC control is implemented with a TMS320F28P650DK high performance microcontroller. The flying capacitor topology is selected over more traditional topologies (for example, Vienna rectifier) due to a frequency doubling effect in the inductors. This doubling results in smaller and higher efficiency inductors. The PFC is followed by two Δ-Δ connected three phase inductor-inductor-capacitor (LLC) converters. There is one LLC for +400V and one for -400V. The LLC converters can be configured as separate supplies or as a single 800V output. The Δ-Δ connection provides reduced root-mean-square (RMS) currents. LLC control is implemented with a single TMS320F28P650DK high performance microcontroller.
特性
- Peak efficiency: 98.5%
- PFC operating frequency: 65 kHz
- LLC operating frequency: 100kHz and 1.5MHz
- Dimensions: 800mm × 160mm × 32mm
