Is it possible to make a halfbridge coilgun with high side IGBT and low side SCRs?
In a rather simple coilgun, the problem of freewheeling current from the coil is solved with a diode in parallel with the coil.
The energy of the reverse current is wasted this way and even slows the ...

Supply of the primary side of the transformer in a forward, half-bridge converter
Why is it that in most forward, half-bridge converters, one of the transformer windings is connected with two capacitors (to VCC and GND):
when my simulations shows that one capacitor (that block DC ...

Only using low side of high/low mosfet driver - can I leave the high pins disconnected?
I have the below circuit for a high/low mosfet driver half bridge, with an extra low side for running a brake resistor (note this is just one of the 3 half bridges for the BLDC controller)
I'm using ...

Half-Bridge with N-channel Mosfets and IR2101
I am building a half-bridge with IR2101 as half bridge driver and I am being confused by something in the datasheet of IR2101. My main supply voltage will be 40V. The VCC of the IR2101 will be 15V ...

Gate spikes in half-bridge IR2110 driven
Some time ago I posted a question about weird oscillograms of half-bridge, gate spikes on mosfet openings. After some investigation, it was revealed that the problem is not in transformer leakage ...

Half-bridge oscillogram spikes, possible shoot through
I built a half-bridge smps based on IR2110S, it is working but the oscillograms seems weird and mosfets are a little hot.
LOW side mosfet Vds.
Two oscillograms, mosfets midpoint as oscilloscope ...

How much voltage must a MOSFET withstand in a half-bridge configuration?
It seems a bit silly and I guess I know the answer but I don't know why it gave me some confusion, in a half-bridge configuration like the one in the image:
If between DC-Bus+ and DC-Bus- there is a ...
