本文将介绍在使用ROHM（罗姆）的SiC-MOSFET驱动用AC/DC转换器控制IC“BD7682FJ-LB”设计的隔离型准谐振转换器中，电源IC用来降压及稳定控制的各种检测用引脚所需部件。

首先来看一下电源IC BD7682FJ检测用引脚功能。BD7682FJ通过FB引脚，ZT引脚，CS引脚来监测所需的位置（点），从而进行降压及稳定控制。

FB（反馈信号输入）引脚通过光电耦合器来监测二次侧输出电压，从而实现稳定控制。ZT（过零电流检测）引脚通过VCC绕组检测开关关断时线圈中积蓄的电力被供应给二次侧输出电容器，且供给电流已达到零。CS（一次侧电流感应）引脚在监测开关（MOSFET）电流的同时，还具有过电流限制功能。

作为整体的工作，通过FB引脚和CS引脚控制开关的导通时间，通过ZT引脚控制关断。

下面介绍各引脚所需的部件。

1、电流检测电阻：R19

R19通过开关晶体管Q1将一次侧的电流转换为电压。该电压由CS引脚监测，并设置输出的过负载保护点。设置R19的值，使一次侧的最大电流Ippk（0.66A）流过时CS引脚的过电流检测电压Vcs＝1V。

→1.5Ω

另外，R19的损耗P_R19为：

考虑到耐脉冲性能，设R19为1W以上。

关于耐脉冲，即使额定功率相同，耐脉冲性能也可能因电阻的结构等而改变。具体请向所用电阻的厂商进行确认。

2、CS引脚噪声保护用电阻及电容器：R22，C13

无法用消隐功能吸收噪声时，可考虑增加RC滤波器。不需要滤波器时，推荐插入R22（1kΩ左右）作为抗浪涌对策。C13为47pF左右。

3、ZT引脚电压设置电阻：R21

R21用来设置ZT引脚的波谷检测电压。ZT引脚的波谷检测电压为Vzt1＝100mV typ.（ZT引脚电压下降时），Vzt2＝200mV typ.（ZT引脚电压上升时）。另外，根据ZTOVP(min)＝3.30V，大致设置为Vzt＝1～3V左右。将R20设置为100kΩ。线圈匝数计算得，Nd，Ns均为8匝。

设置为时，

则 →12kΩ

4、ZT引脚电容：C11

C11是用来稳定ZT引脚和调整波谷检测时序的电容器。确认ZT引脚波形，波谷检测时序后进行其电容设置。在本电路示例中，选择47pF。

5、FB引脚电容：C12

C12是用来稳定FB引脚的电容器。推荐1000pF～0.01µF左右。在本电路示例中，选择2200pF。

【经验】电源控制芯片BD7682FJ用于高频反激式准谐振开关电源的设计原理和电路电流过零点检测过程

要实现高频化，必须降低开关损耗，软开关技术是一个减少开关损耗的重要方法，其通过谐振的方法将开关电源中开关MOSFET管的电压或电流按照正弦或准正弦的规律变化，使MOSFET管开通关断时损耗为零，从而提高开关频率。本文为用户介绍罗姆电源控制芯片BD7682FJ在高频准谐振反激式开关电源上设计应用的整体原理和控制电路电流过零点检测的过程。
