“…Power losses in power converters can be split between conductive and switching.. Conduction losses for transistor (7) and diode (8) are obtained by multiplying the current by the voltage drop, which is obtained from a look-up table provided in the transistor data sheet [13]:…”

“…These methods are mostly focused on thermal stabilization rather than on the decrease in temperature of a particular component of the inverter. There are various PWM strategies that enable a decrease of switching losses in the system [6]- [8]. In [9] the model predictive control strategy was used to redistribute losses from the hottest power module to the coldest, but this method is limited by the conventional threephase inverter applications with sinusoidal shape of the output current.…”

Air-cooled heatsinks for electric drives often suffer from unbalances in the heat dissipation capability when several power modules are mounted on the same heatsink, eventually limiting the output power to that dictated by the hottest module. This paper discusses the options for the placement of the power modules on the heatsink for the particular case of switched reluctance drives. Combined with active thermal control methods, this reduces the temperature dispersion, and therefore allowso toincrease the maximum output power of the converter.

This paper discusses the approach for the witching loss minimisation in a 3-level inverter. It utilises a model predictive method which is used for evaluation of both the switching loss and voltage unbalance. The method is based on the cost functions implemented to provide simultaneous minimisation of loss and DC link voltage balance control. The simulation results shown that the total loss is reduced in 15% compared to a standard PWM strategy for a 3-level inverter operating at PWM frequency of 16 kHz.

Continuous pulse width modulation (CPWM) and discontinuous pulse width modulation (DPWM) strategies are used to control voltage source inverter operation. CPWM strategies allow for the reduction of total harmonic distortion values, while DPWM strategies provide a more effective reduction in inverter switching losses. The paper is devoted to the problem of improving the three-phase voltage source inverter efficiency by a controlled transition from CPWM to DPWM. The article proposes an adjustable discontinuous pulse width modulation (ADPWM) method, which means a transition from space vector PWM (refers to CPWM strategies) to DPWM in all inverter phases when the switches’ temperatures exceed the allowable value in at least one of the inverter phases. The method flowchart is presented and an algorithm for modifying the envelope curve within one sector is given. In order to test the ADPWM method a Simulink-model of a three-phase voltage source inverter and its control system were developed. A study of the proposed ADPWM method’s efficiency in comparison with CPWM, PCDPWM and NCDPWM methods was carried out using a Simulink-model. It was established that the proposed ADPWM method provides dynamic losses reduction in the inverter switches by 2.86 times compared to CPWM and by 1.89 times compared to PCDPWM and NCDPWM methods. Power supply systems for medium and high-power AC motors provide a promising area for application of the proposed ADPWM method.
