A single high-boost HAM may be used with any combination of V375 series DC-DC converters which are available in Micro, Mini and Maxi packages with up to 600 Watts of output power. Versions without internal diode bridges (HAMD and BAMD) can be operated in parallel to provide power expansion capability. The combination of the high-boost HAM with V375 DC-DC converters results in a power conversion system with twice the power density, fewer components and lower cost compared to previous HAM-based solutions. In addition, the high-boost HAM is fully compatible with Vicor’s VI-26x and VI-J6x series DC-DC converters. This gives designers the freedom to choose from the industry’s broadest selection of DC-DC converters with outputs from 2 to 95 Vdc, 50 – 600 Watts. The user need only provide external hold-up capacitors, a few discrete components, and a line filter (available from Vicor).

The incoming AC line is rectified and fed to the boost converter. The control circuitry varies the operating frequency of the boost converter to maintain the output voltage of the HAM above the peak of the incoming line, while forcing the input current to follow the waveshape and phase of the line voltage. The AC input current follows the voltage waveform and a power factor better than 0.99 is achieved. Operating efficiency of the boost converter is optimized at any incoming line voltage by an adaptive output voltage (Figure 3) control scheme. ZCS Boost Converter Rectifier AC Line Inrush & Short Circuit Protection Current Sense High Frequency Control Output Voltage Control Module Enable & Housekeeping Power OK Circuitry Voltage Waveform Gate In Gate Out The output voltage of the HAM is a function of incoming AC line voltage (Figure 3). On a nominal 115 Vac line, the output voltage of the HAM is 280 Vdc — well within the input operating voltage range of Vicor V375 DC-DC converters. Above 180 Vac input, the output voltage linearly increases with input voltage. At 230 Vac the delivered voltage will be approximately 365 Vdc. For any given input line voltage, the HAM maintains enough headroom between the output voltage and peak input voltage to ensure high quality active power factor correction without sacrificing operating efficiency. + DC Out – Note: Non-Isolated Output Without PFC Aux.

Figure 4 — Connection diagram HAM / DC-DC converters PIN FUNCTION / DESCRIPTION L1 and L2/N (HAM) An appropriate line filter is required to limit conducted emissions and ensure reliable operation of the HAM, see page 8. Connect single phase AC mains to the input of the line filter via a 10 A, 250 V fuse. Connect the output of the filter to L1 and L2/N of the HAM. Do not put an X-capacitor across the input of the HAM or use a line filter with an X-capacitor on its output as power factor correction may be impacted. +IN, –IN (HAMD, BAMD) These pins are connected to the output of the external bridge rectifier in HAMD / BAMD configurations (Figure 5). GATE IN (HAM) The user should not make any connection to this pin. GATE IN (HAMD) This pin provides line voltage envelope and phase information for power factor correction. This connection must be made through the synchronization diodes between the line filter and bridge rectifier (Figure 5). GATE IN (BAMD) The Gate In pin is an interface pin to the Gate Out pin of a HAMD or BAMD depending on configuration. The user should not make any other connection to this pin. GATE OUT The Gate Out pin is a synchronization pin for HAMD/BAMD arrays; the user should not make any other connection to this pin. +OUT and -OUT Connect the +OUT of the HAM to the +IN of the respective Vicor DC-DC converters with the recommended fuse. Connect the -OUT of the HAM to the -IN of the converters. In addition, an external hold-up capacitor of 1,000 µF with a minimum voltage rating of 450 Vdc, is required (across the output of the HAM) for 16 ms ride through time at full power (500 µF for half power, etc). This capacitor must be in close proximity to the HAM. Do not exceed 3,000 µF of total output capacitance. Lower values of capacitance may be used for reduced hold up requirements, but not less than 500 µF. Lower capacitance values may degrade power factor specifications.

A/S The HAM provides a low voltage non isolated output Auxiliary Supply (A/S) that may be used to power primary side control and monitoring circuitry. This output is 19 – 23 Vdc, referenced to -OUT, at 3 mA max. Do not overload or short this output as the HAM will fail. A typical use for A/S is to power an optical coupler that isolates the Power OK signal (Figure 6). E/O The Enable Output (E/O) is used to inhibit the DC-DC converters at start up until the hold up capacitors are charged, at which time Enable is asserted high (open state, Figure 8). If the AC line fails, E/O goes low when the DC output of the HAM drops below 250 Vdc. The E/O pin ancillary circuitry illustrated in Figures 4 and 5 provides transient immunity. The illustrated circuitry is the minimum required, see Figures 4 and 5. +OUT P/OK E/O + A/S – –OUT IAS ≤ 3 mA 19 – 23 V "Power OK" Status Low = OK E/O must be connected to the Gate Input of all VI-26x and VI-J6x drivers and / or the PC pin of the V375 DC-DC converters (Figure 4); failure to do so may cause the converters to toggle on and off. If an external load is connected directly to the output of the HAM, do not apply the load until the output hold up capacitor(s) are fully charged. +OUT P/OK E/O A/S In applications using VI-26x drivers and VI-26x boosters, the E/O pin should be connected to the Gate In pin of the driver module only, it is not necessary to connect this pin to boosters as they are controlled by their respective driver. DO NOT OVERLOAD or directly connect a capacitor to the A/S terminal. –OUT Figure 6 — Auxiliary Supply (A/S) VI-HAM™, VE-HAM™ Rev 2.6 vicorpower.com Page 6 of 10 4/2013 800 735.6200 18 kΩ, 1/4 W VxHAMxL PIN FUNCTION / DESCRIPTION (CONT.) P/OK Power OK is a monitor signal that indicates the status of the AC mains and the DC output voltage of the HAM. P/OK is asserted (active low) when the output bus voltage is within normal operating range (>270 Vdc) and 20 – 25 ms after DC-DC converters are enabled by the E/O signal of the HAM. This provides sufficient time for the converters to turn on and their output(s) to stabilize prior to P/OK being asserted, (Figure 9). For momentary interruptions of AC power, the HAM will provide at least 16 ms of ride through or hold up time (with 1,000 µF output capacitor). On loss of power or brownout, +OUT D LOGIC P/OK (when the HAM output voltage drops below 270 Vdc) the P/OK signal will go to an open circuit state (Figure 7), signaling an impending loss of input power to the converter modules. P/OK will provide power fail warning at least 1 ms prior to converter shut down. When the HAM output voltage drops below 250 Vdc the converters are disabled via Enable Output (E/O).

It also presents a well defined high frequency AC line impedance to the input of the HAM. To meet the listed specifications, Vicor’s P/N 30205 line filter/transient suppressor or equivalent must be used, see Figure 10.
