常见问题

What is the difference between microcontroller and microprocessor in power supplies?

Microcontrollers integrate CPU, memory, and I/O on a single chip for dedicated control tasks, while microprocessors require external components and are better for general computing. Microcontrollers are preferred in power supplies for their lower cost, lower power consumption, and real-time control capabilities.

How do microcontrollers ensure safety in programmable power supplies?

Microcontrollers implement hardware watchdogs, over-voltage/current protection algorithms, temperature monitoring, and comply with safety standards like IEC 60730 Class B for functional safety in household appliances and industrial equipment.
