1. INTRODUCTION This application note deals with the design of a 3-Phase auxiliary power supply for 150W dual output SMPS, using the L5991 PWM driver and the STC08DE150 ESBT as main switch. The combination of these ST's parts aims at obtaining a high efficiency solution for high DC input voltage, typical requirement of any three phase application.
Three-phase inverters function as variable-frequency drives to control the speed of AC motors and for high power applications such as HVDC power transmissions. The typical application of a three-phase inverter using six isolated gate drivers is shown in Figure 1.
The typical application of a three-phase inverter using six isolated gate drivers is shown in Figure 1. Note that each phase uses a high-side and a low-side IGBT switch to apply positive and negative high-voltage DC pulses to the motor coils in an alternating mode.
Such a control law can enable a solar inverter auxiliary power supply that maintains efficient operation regardless of environmental conditions. It is possible to mitigate the challenges of designing an effective auxiliary power supply with the proper flyback controller.
