► Brief Introduction

 

Power supply is an important part of the system, consisting of power board, backlight board, battery and fan.

The main power board converts the AC mains input into 5V and 12V DC to energize other parts of the system. Similarly LCD display requires particular supply, for which case a backlight board is supplied. The battery could maintain the formal function of the system for a short period when AC mains is disconnected. A small fan requiring DC input is used to realize superior ventilation.

Introduction to Principle

 

This module converts 220V AC mains or battery power into 5V and 12V DC supplies to power other boards. If AC mains and battery coexist, the former take the priority to power the system and charge the latter at the same time.

1. AC/DC

Convert high-voltage AC supply into low-voltage DC supplies to power subsequent circuits and charge the battery.

2. Battery Control Circuit

If AC mains and battery coexist, this circuit controls the output from AC/DC part to charge the battery. If AC mains is disconnected, this circuit controls the battery to power the subsequent circuits.

3. 5V DC/DC

Convert the DC supply from the previous circuit into stable 5V DC supply to power other boards.

4. 12V DC/DC

Convert the DC supply from the previous circuit into stable 12V DC supply to power other boards.

5. Power Switch Circuit

Control the working status of 5V DC/DC and 12V DC/DC in order to control ON/OFF action of the patient monitor.

6. Voltage Detect Circuit

Detect the output voltages of various parts of the circuits; convert the analog signals into digital signals and send them into main board for further processing.

 

Testing key points

 

After connecting AC mains, the DC voltage over C12 is about 1.3 ~ 1.4 time of AC input voltage; voltage over C15 is 17.6V. Voltage over C24 is 13.8V when battery is disconnected.  Voltage over C47 is 5V applied to power U7, U8 and U9. Voltages of pin8 of U1, pin8 of U10 and pin11 of U11 to the ground are all 5V. Voltage of pin2 of U10 to the ground is 2.5V. On the oscillograPHiliphhilip, we can observe that voltage waves of pin4 of U11 and pin4 of U10 to the ground are standard toothed waves of 120kHz oscillating frequency. Voltage waves of pin1 of Q1 and pin1 of Q5 when output is connected with rated load are square waves of about 120kHz frequency. Voltage wave of D16 is a square one of about 280kHz frequency.
