### How to determine the efficiency value of the inverter we design?

tl, dr: For a bench setup get true RMS power meters for both the DC and AC side, and measure over a variety of load conditions. Option: use a 4-channel scope with math capability. These typically also ...

### Converting 12 VDC to 24 VDC @ 6000 Watts

Divide and conquer. Resistive losses scale as the square of current so splitting up your 250A minimizes the amount of 2/0 or 3/0 gauge wiring you'll need to work with. The last system in that range ...

### How do traction inverters behave during regenerative braking?

Agree with the answer from Andy. I want to share more information: First, refer to below photo, you can see there are two quadrants that energy can flow to Battery, II and IV. And Torque * Speed is ...

### How do traction inverters behave during regenerative braking?

I've added green arrows to show the direction of current at a particular instant in time when the most positive terminal from the motor is indicated by the red circle and, the most negative motor ...

### 3500 Watt Inverter current runaway

This is the power drawn by the water heat pump I use for heating. It starts around 5kW, then increases to 6kW as water temperature in the heating circuit rises. $\Delta T$ is the temperature ...

### High voltage supply MOSFET inverter

Many possible ways to make it happen. Here is one with only discrete components: The downside is that it will consume a few mA of current as long as the battery is connected.

### High voltage supply MOSFET inverter

It's an analog system the will enable that chip (max5035). Image from the datasheet. As you can see, the MAX5035 has an enable input (on/off) that you can use. Replace the switch with a MOSFET and ...
