PTC Ceramic Air Heater

PTC Ceramic Air Heater

 

1、Product Introduction

 

The heater part of the PTC heater assembly is located at the bottom of the heater and is heated according to the characteristics of the PTC plate. The battery works with high-voltage electricity, the PTC plate produces heat and the heat is transferred to the heat-dissipating aluminum strip, after which the fan blows air, blows the surface of the cooler, the heat is removed and it shocks. hot air The stove has a compact structure, reasonable layout, and it uses the space of the stove as efficiently and safely as possible. Attention has been paid to the sealing and installation process of the stove in the design to ensure normal operation of the stove.

3、Main functions

Control function

Can realize PTC switch function;

Can realize PTC duty cycle control.

 

Security function

Hardware protection;

Software protection.

 

4、PTC drive circuit

Low side IGBT and drive circuit
4 groups of PTCs are independently controlled by 4 IGBTs. If some of the PTCs have an open-circuit fault, the system can continue to work with derating, effectively increasing the reliability of the system;

 

Current sampling circuit
Shunt (sampling resistor) is used as the main acquisition device, and the differential amplifier circuit is used for signal conditioning, which can effectively reduce interference and improve data accuracy. The two areas use independent sampling resistors to realize partition power and protection functions separately.

 

Current Comparator and Limit Circuit
This current comparison circuit is mainly used for load short-circuit detection, and its response speed is very fast, which can ensure the safety of the system. The dual-zone also adopts an independent protection circuit.
