本文提出一應用於電動車及混合電動車之具有雙模式控制的新型電機驅動整合電路。提出之整合電路可以使永磁同步電動機動作於馬達模式或是當作升壓電路之升壓電感，進而提升輸出轉矩且耦合於相同的傳輸系統或是提升連接於整合電路之變頻器的直流鏈電壓。在馬達模式下，提出之整合電路動作於變頻器；而整合電路動作於升壓型轉換器時，將利用馬達繞組當作升壓電感，進而提升轉換器的輸出電壓。
此外，於升壓模式下，提出一可提升效率之應用於整合電路的新型控制技術。提出之控制技術係在重載時，利用交錯式控制可以顯著的減少電流漣波，進而降低損失以及熱應力；相比之下，於輕載時，使用單相控制可以避免增加額外的切換損失以及導通損失。
實驗結果由數位訊號處理器控制一3 kW變頻器/轉換器來驗證其升壓比可以從1.25至3。於滿載情況下，效率可以達到93.83 %，且馬達溫度均能夠維持於室溫；這些結果充分的驗證了本文所提出之整合電路的優點。

A new integrated circuit for motor drives with dual mode control for EV/HEV applications is proposed. The proposed integrated circuit allows the permanent magnet synchronous motor to operate in motor mode or acts as boost inductors of the boost converter, and thereby boosting the output torque coupled to the same transmission system or dc-link voltage of the inverter connected to the output of the integrated circuit. In motor mode, the proposed integrated circuit acts as an inverter and it becomes a boost-type boost converter, while using the motor windings as the boost inductors to boost the converter output voltage.
Moreover, a new control technique for the proposed integrated circuit under boost converter mode is proposed to increase the efficiency. The proposed control technique is to use interleaved control to significantly reduce the current ripple and thereby reducing the losses and thermal stress under heavy-load condition. In contrast, single phase control is used for not invoking additional switching and conduction losses under light-load condition.
Experimental results derived from a digital-controlled 3-kW inverter/converter using digital signal processing show the voltage boost ratio can go up to 1.25 to 3. And the efficiency is 93.83% under full-load condition while keeping the motor temperature at the atmosphere level. These results fully confirm the claimed merits for the proposed integrated circuit.
