Power converter components are selected such that it operates inherently (without any control) in a constant, maximum power mode over a wide range of the load current. This mode keeps the conduction loss low and in combination with the ZCS for the active devices provides high power conversion efficiency. A complete analysis of the circuit with a finite output inductance value is done. Produced graphical results show that constant power mode can be provided by an appropriate design of the output inductor. Less than 6% variation of the output power is experimentally achieved in the noncontrolled converter for more than 50% variation of its output current. The constant power mode is practically implemented in a 600 W, 130 kHz, phase-shift controlled bridge arrangement of the quasi-resonant buck converter. This converter circuit is very robust, operates in a ZVS mode for the MOSFETs and ZCS for the output rectifiers and features more than 95% efficiency.","PeriodicalId":287192,"journal":{"name":"APEC '99.

An automatic transition into flux weakening is achieved by controlling the reference voltage magnitude. The fifth and seventh stator current harmonics of the fundamental frequency, generated in the over-modulation and six-step modes, propagate through the current control loops, resulting in the sixth harmonic in the reference voltage and deteriorating drive performance. To filter the sixth harmonic, an adaptive lattice-structure allpass-based notch filter is employed, providing minimal phase delay and complete attenuation of the sixth harmonic.","PeriodicalId":287192,"journal":{"name":"APEC '99.
