Heat Sink Requirements
heat sink required for various output power levels and pulse-
width-modulated (PWM) switching frequencies. Maximum
total losses of the unit are also shown. This data is based on
the following key operating conditions:
rectifier and inverter occur at full pulse-width-modulation.
These losses set the maximum continuous operating
temperature of the heat sink.

follow the instantaneous fluctuations of the output current.
Thus, peak junction temperature rise increases as output
frequency decreases.

Over Temperature Protection
thermistor included in the power module for thermal
sensing. Protection circuit that initiates a shutdown if the
temperature of the IMS substrate exceeds a set level can be
implemented. The nominal resistance vs. temperature
characteristic of the thermistor is given in Figure 5.
Voltage Rise During Braking
regenerative braking, forcing the bus voltage to rise above
the level defined by the input voltage. Deceleration of the
motor must be controlled by appropriate PWM control to
keep the DC bus voltage within the rated maximum value.
For high inertial loads, or for very fast deceleration rates,
this can be achieved by connecting an external braking
resistor across P and BR and controlling the brake IGBT
switching when the bus voltage exceeds the allowable limit.
Over temperature can be detected using the NTC
The motor will feed energy back to the DC link during
