This paper presents the family of the single-inductor multi-output DC-DC converters. Conventional transformer-based multi-output DC-DC converters are proposed to provide multiple output voltages, which, however, have the drawbacks of high cost and large volume. Therefore, the single-inductor multi-output three-terminal configuration is developed in order to reduce the component count and cost for...
When a low voltage DC power source is used, a DC-DC converter with a high step-up voltage gain is required to raise the voltage to more applicable levels. This is typically achieved in classical converters which often have to be driven by pulse width modulation (PWM) waves with extremely high duty cycles. Although theoretically step-up converters can achieve an infinite gain as the duty cycle approaches...
This paper presents the system modeling and analysis of the single-phase current regulation module (CRM) in continuous-conduction-mode (CCM) at steady state for use in the electrical discharge machines (EDMs). Based on the equivalent model of the three-terminal PWM switching cell, the small-signal equivalent circuit models of the single-phase CRM are obtained to derive the corresponding open-loop...
