5.1 Input EMI Filter and Protection

This section contains a single stage input EMI filter with a 5A, 1000V fuse. The filter is based around a Common mode choke with X-caps for Differential mode noise attenuation and Y-caps for Common mode noise rejection. MP201 and MP202 are input power connections, while J200 and J201 maybe used as voltage sense lines for power efficiency measurements.
