Hi all,
I have a short question. What are the pros and cons for the half-bridge topology compared to the single ended one in induction cookers?
Thanks in advance!

Hi,
The half bridge topology offers quite some advantages compared to the SEPR topology, but also some disadvantages:
Pros:
↑ Very good power efficiency for wide load range (capacitive operation with ZV-turn-off and ZV-turn-on)
↑ Easy to control due to stable VCE voltage
↑ Higher reliability than SE due to less sensitivity on control errors
↑ IGBT are operated from rectified line -> lower voltage class IGBTs can be used
↑ Higher output power capability -> no limitation for output power
↑ Continuous operation at lower power levels
Cons:
↓ More expensive than SEPR due to two power switches and Half Bridge Driver
↓ Larger heatsink and PCB needed
I hope this can help you for deciding which topology to choose.
Best regards,
Thomas Wurzer
