typical simple SMPS itu power factornya 0.6-0.65, dan tanpa harmonic
supression. Waktu kuliah kerjaannya design beginian soalnya.
Oleh karena itu jaman sekarang SMPS kudu adhere IEC 555-2. Nah kareha
ada PFC dan Harmonic supression, itu makanya anda lihat modern SMPS
sekarang bisa punya PF hampir 1.
