Description

Block Half-Bridge (Ideal, Switching) simulates a half-bridge with perfect switches and a thermal port. To select the ideal switching device, set the parameter Switching device meaning MOSFET, IGBT or GTO.

A built-in protective diode can be installed for each switching device. The built-in diode protects the semiconductor device by providing a reverse current transmission channel. An inductive load can cause a high reverse voltage surge when a semiconductor device suddenly cuts off the voltage supply to the load.

The best option is to simulate the diodes inside the unit. Half-Bridge (Ideal, Switching). For external modeling of diodes, model them without taking into account capacity or charge.

Switching losses

For information on how the block simulates power-on and power-off losses, see the description of the blocks. MOSFET (Ideal, Switching), IGBT (Ideal, Switching) or GTO, depending on the value you have selected for the Switching Device parameter. The main difference between how these blocks and the block model losses is Half-Bridge (Ideal, Switching), is that for the values of MOSFET and IGBT, block Half-Bridge (Ideal, Switching) does not use the Use last on-state current from previous cycle for turn-on loss or Use last off-state voltage from previous cycle for turn-off loss parameters. The reason for this difference is that the block Half-Bridge (Ideal, Switching) It does not simulate the capacitance of the diode or the inductance of the pins, as it is designed for fast simulation using perfect switching. Modeling both switching devices in one unit avoids the difficulties associated with measuring current in the on state and voltage in the off state during reverse diode recovery, so you do not need a physical model of the diode charge. The unit measures the forward current of the diode and the voltage in the off state at the time of giving the command to turn off the additional switching device.

By default, the unit applies switching losses only to the heat node, increasing the node’s temperature by the required amount. To get the necessary power due to losses when switching from the power supply, select the checkbox Apply switching losses to electrical supply.

Instantaneous application of switching losses to a power source is mathematically impossible, so the unit applies switching losses for a period equal to the value specified for the parameter. Averaging period for switching losses. Set this value to the pulse width modulation (PWM) period of the gate driver.

For all ideal switching devices, the heat losses in the recorded simulation data are represented as E_last_turn_off_losses, E_last_turn_on_losses and last_reverse_recovery_loss. These variables include losses in the form of a pulse with an amplitude equal to the energy loss. If you are using a script to summarize the total losses over a specific simulation period, you need to summarize the pulse values for each leading edge.

You can also access the total accumulated switching losses for each of the two switching devices from the corresponding variables. accumulated_switching_losses_event in the registered simulation data. These variables sum up all switching losses at the current moment, including reverse recovery losses for the diode.

Variable power_dissipated The recorded simulation data does not take into account switching losses, since the block models these losses as instantaneous events. Variable power_dissipated displays ohmic losses when switched on.

When using a fixed-step solver, the minimum on or off pulse that supports recording switching losses is three time steps long. If the pulse is shorter than three steps, the unit does not register switching losses.

If you are using tabular data to model switching or reverse recovery losses, make sure that the temperature, current, and voltage are within the range you specify. If you do not specify a realistic thermal model, for example, if the mass of the joint or the conductivity from the joint to the housing is too low, the temperature may exceed the range you specify, which will lead to extrapolation of losses by the unit to non-physical values.

Thermal port

Use the thermal port to simulate the effect of the generated heat and the temperature of the device.

The thermal port H can also be divided into two separate thermal ports connected to the upper and lower switching devices by checking the box Separate thermal ports for upper and lower devices. If you separate the thermal ports for the upper and lower devices, you can also separate the thermal ports for the built-in diodes of each switching device by checking the box. Separate thermal ports for integral diodes. The upper and lower switching devices have the same thermal parameters.

This figure shows the block icon that is displayed when all thermal ports are opened.:

Limitations

  • If for the parameter Switching device the value is set GTO The block assumes that the current change in the load between PWM cycles is small. This assumption implies that the load inductance or switching frequency is large enough to smooth the current.

  • If the check box is selected Apply switching losses to electrical supply, it is necessary to connect the power supply to the half bridge. For example, you need to uncheck the box Apply switching losses to electrical supply if your model has a switch that can disconnect one or both contacts of the power supply. There may also be problems with numerical initialization if the power supply is not initialized when it is switched on, for example, due to a smoothing capacitor that starts at zero charge.

Details

Vector is a string of values of the thermal mass, where — the number of Kauer elements used in the heating network.

If for the parameter Thermal network the value is set Cauer model parameterized with Foster coefficients, the default value is — [33, 50].

Dependencies

To use this parameter, set for the parameter Thermal network meaning Cauer model parameterized with Foster coefficients, and for the parameter Thermal mass parameterization meaning By thermal mass.
