CHAPTER 3 : SYSTEM APPLICATION GUIDANCE

3.1 Application guidance

This chapter states the DIPIPM+ application method and interface circuit design hints.

3.1.1 System connection

C1: Electrolytic type with good temperature and frequency characteristics
(note) The capacitance also depends on the PWM
control strategy of the application system
C2: 0.01μ-2μF ceramic capacitor with good temperature,
frequency and DC bias characteristics
C3: 0.1μ-0.22μF Film capacitor (for snubber)
D1: Zener diode 24V/1W for surge absorber
AC line input

T
Z C
Z : Surge absorber
C : AC filter(ceramic capacitor 2.2n -6.5nF)
(Common-mode noise filter)
