2 Topology Selection Process

These metrics were considered at the start of the project to select overall system architecture, including primary and secondary side topologies:

• Component count and price
• EMI/ Filtering requirements
• Complexity and cost of magnetic components
• Power density
• Peak efficiency vs overall system efficiency for wide input voltage range
• Special requirements: High voltage, high current and isolation for safety
• Soft-switching operation (Zero-Voltage and Zero-Current switching)
• Snubber requirements
• Suitability for application and operating profile. For example, battery charging requires voltage and current control (CV, CC operation).
• Requirements for bidirectionality
• Control complexity and control output requirements
• Fixed vs Variable frequency operation
• Multiphase and current sharing for parallel operation
